I couldn't really let today go by without mentioning Jose Mourinho's dramatic departure from Stamford Bridge, and what it might mean to the club and the Premiership moving forward.

There is a certain sense of irony that at the beginning of the season, the press were having a field day claiming that Arsene Wenger would leave Arsenal, and his assembled team would break down, leaving the club in oblivion. Of course it was all absolutely ridiculous, but that won't stop them using the same sensationalist tactics down the road in West London.

There is no doubting that Mourinho leaving will shake Chelsea to the core, and will unsettle a number of players. However, I don't think for one moment there will be the mass walkout that some papers are already predicting, with Lampard, Drogba and Carvalho all being tipped to swiftly follow the manager out. Much like when Wenger leaves, there will be some changes as a new manager puts his stamp on the club, and over the first year a couple of players may decide to draw their Chelsea careers to a close and move on. And they will be replaced.

Of course, that scenario isn't interesting enough for the media, who just want to print 'Crisis!' and 'Turmoil!' whenever they can.

But that isn't to say that this is not bad news for Chelsea. It is. Mourinho may have been one of the most dislikable managers ever to walk these shores, but as a tactician and man manager he was up there with the very best. Some may say that he bought the title, but as many Real Madrid managers will testify, collecting players and then moulding them into a cohesive team is an extremely difficult job. Every player at the club now believes he is a superstar, and superstars don't often like change.

Mourinho made Chelsea incredibly difficult to beat, and he infused a siege mentality in the team which led to so many fightbacks - they just didn't know how to lose. Witness the comeback against us at the Emirates at the end of the last season - a goal and a man down in the second half, they battered us.

Many are already writing his apparent successor, Avram Grant, off. Clearly the media don't learn that just because they know little about a man, doesn't mean they have no talent. Our own manager was proof of that, and Grant comes with a decent reputation from his time in Israel especially.

But this is a wholly different animal. He is friends with Abramovich, so he is likely to bend to his wishes more often that Jose did. Shevchenko can expect more playing time. But at the same time, there may be some resentment around the club, and the fans are ready to lash out if things don't go to plan. For me, the job is now a poisoned chalice - it is a practically impossible task to achieve the same level of results as Mourinho while appeasing Abramovich with attractive football. The players have to learn a whole new style - can they do it? Do they even want to?

The timing is also extremely odd. With a crunch game at Old Trafford on Sunday, they will go one of two ways. Either they will act unsettled and get rolled over, or Mourinho's siege mentality will live on and they'll shock United. I suspect the latter, especially after their awful performance on Tuesday - they have a point to prove.

It has been a bright 24 hours for Arsenal. It has been a disheartening 24 hours to be a Chelsea fan. This season gets more interesting by the day.

Well, that'll teach me not to be confident about our chances. Thinking that a draw in last night's opener with Seville would not be an awful result, I predicted a 2-2 scoreline. How wrong I was.

The first half hour was fairly cagey, the only notable action being that Fulop, the Seville keeper, seemed particularly dodgy with his handling. Encouraged by this, Van Persie, Flamini and Adebayor all had pops from distance, and when Cesc tried his luck, Escude gave the errant shot a huge deflection, putting Arsenal one up. It was a goal straight out of the Frank Lampard locker.

The goal seemed to settle the team, and Toure should've doubled the advantage from a corner but seemed to run beyond the ball, almost having his back to goal as he twisted in a futile attempt to make a decent connection.

The second half didn't start well, Rosicky going off with another hamstring injury. Although Wenger said he'd be ruled out for at least two weeks, with his history I'd be surprised to see him back in twice that time.

But soon after that setback, the lead was doubled, a Fabregas freekick delicately flicked on by Sagna for Van Persie to smash home from close range. In truth, the goal owed a lot to some pretty slack defending, but credit where it is due - we are beginning to look threatening from set pieces again, something you could rarely say last season.

After that everyone relaxed a little, and despite Seville having a couple of chances, mainly to Kanoute, they were never a serious threat, and the players eased into passing the ball around and through their Spanish counterparts, until in injury time a beautifully slick move saw substitute Eduardo slide in a third. He gets into some excellent positions and is rewarded by accurate passing. If he keeps that going he will continue to score plenty for this club.

Although the first goal came about via a huge slice of luck, and the second killer goal was poorly defended, it was an excellent performance, if not quite the spectacular one some papers would have you believe this morning. Flamini and Sagna especially were everywhere, bustling into the opposition and flying around the field, while Fabregas roamed around efficiently in the centre, playing intelligent passes whenever he got the ball. Up front, Adebayor put in all the hard work, he deserved the generous applause when he came off, while Van Persie also looked more of a menacing threat.

Almunia didn't have a lot to do at the back, but coped fine with the couple of shots that came his way. His handling was a touch suspect, twice letting balls squirm away from him that on another day could be costly, but for me he's doing fine right now.

There is a huge amount of excitement around the club right now, and rightly so, but we have to check and say that things are going our way at the moment. While the performances are excellent, we had some luck last night and on Saturday, so we need to remember that when the luck turns, as it undoubtedly will at some point. What is important to see is the fire in this team, the drive to win, and the fight that lasts for ninety minutes, as shown by the continual stream of late goals. Scoring at the death is a happy habit to get into.

The Chelsea situation needs to be covered by another article, but for now, enjoy the present, because it's rare to see any football team clicking like ours is at the moment.
