Yes our Arsene needs to get to the end of the season, take a big breath and let it out again, then go away from football completly for a month.
Then return, hopefully refreshed, and spend the money, that has been there for the last two seasons, on players who will push most of this team on to the next level. A goalkeeper who can kick a ball, wo central defenders, a true leader/captain who can operate in the middle of the park, and particularly a striker who will grind out as many goals as he will score spectactually.
And finally he should sell all those players who have indicated they want to be away fom Arsenal - including if necessary Fabregas although i'm not sure Barca are still so keen and wouldn't pay the price - and at least 10 of the 18 players out on loan. All of which should contribute nicely to a large pot to bring in some real proven quality at the highest level.
So simple I can't understand why an intelligent and successful manager like Arsene can't see it ... simples
