For me Coq hasn't got a future at Arsenal, neither unfortunately has Diaby as much as I'd like him to 'make it' I just don't think his body is going to hold out over the long term. Arteta is a quality player but he is 33 this year, Rosicky will be 34. Kallstrom won't be at Arsenal next season and Ox is technically a forward.
So that leaves Ozil, Ramsey, Wilshere and Cazorla. Three of those four spent a significant part of the season injured and Santi was out of form for huge parts of the season, so I definitely think there's room for Fabregas.
It would be a bit of a luxury I admit and a Striker and DM are a priority but given his quality we'd be mad to turn him down if there was a chance he'd re-sign.
we should buy fabregas if he is available as we should have more quality in the squad to cover for injuries/drop in form, and for us to be strong ALL season in ALL competitions.
we would then be able to choose from Cesc, ozil, santi, Rambo, Jack, rosiky, Arteta, Flamini, and Diaby.
it would mean that one area of team is properly covered.
if we buy Cesc then we can rotate midfield or play in different formations, and that would then make the opposition think more how to set up against us as we are too predictable. when Cesc plays we can play Ozil up top as number 10, or we could play Cesc up top as fake 9 or as a 10. or play ozil/cesc/rambo
we need to buy all quality players when they become available and not when we are desperate to buy, and so that we we grow the squad.
imo we need to buy 2 strikers, 1 winger, 1 back up goalie, 1 CB
we need forward line of Giroud, sonogoalsyet, new striker world class, new striker first class, new winger, gnarby, theo, ox, podolski. that gives us forward options.
buy a CB who can play RB or a RB who can play CB - i know sagna is available for free !!! oh i forgot we let him go !!
PS what about bidding £50 million for Suarez to start ball rolling, and a cheeky bid for Hazard, Rooney and Yaya Toure just to stir it up a bit
