Thing is Wenger never learns and tactically he hasn't a clue.
You'd think he'd learn from playing a high line against Bale/Lennon, Aguero, Hazard/Schurrle/Salah, Sterling/Sturridge/Suarez and worst of all Messi down the years but I guess not.
Yesterday was the most one sided game I've ever seen from a supposed title contender v a supposed title contender. Even the United 6-1 at Old Trafford when Dwight Yorke ran riot wasn't as bad as that IMO, nor was City's 6-1 at Old Trafford. Chelsea literally could have scored double figures yesterday.
I think Wenger has learnt. There's no doubt he is stubborn but when he really needs to he has adapted, much to my surprise. At the end of last season and the beginning of this season his side's played fast, more direct football, which is an easier style to play, and it quickly got them results. On top of that he showed an uncharacteristic desire to see games out. How many times have we seen Arsenal end a game with 6/7 defenders on the pitch when they're winning? It happens everytime but it's not something he used to do, it used to be all about getting more goals up until the last minute.
The trouble is that he's still trying to revert back to his preferred style when things start going better. Lots of coaches do this in all sports. I was reading the new Malcolm Gladwell book recently and in it he wrote about a college basketball team that was getting beaten every year due to having a poorer quality team. One time he set his team up to play a full court press all game and it worked getting them the win but instead of building on it the coach went back to playing a normal game and the team went back to getting beat all time. It makes no sense logically but there's always a tendency to want to play the game the sameway as the best do.
Typical.
