Optimist view: we sign Witsel, Carvalho, Mata, Koulibaly and Begovic while also shedding some less useful players.
Pessimist view: we get none of those and lose Stones (city), Rom (Chelsea), Del (Barca) and Funes Mori (Roma) while managing to hold onto McGeady, Kone and Niasse.
Reality will be in between. While I am hopeful that multiple people on the optimist side of the ledger sign, I think rumors about Gueye, Sigurdsson, Williams and the like suggest we are preparing for the possibility they do not, as is only proper.
It is if we cannot get our primary targets that Walsh will really earn his money. If plan "a" players don't sign by week one expect a hard push for plan "b" players, while contact begins to be made with the plan "c" group.
While I am as frustrated (and yes concerned) as the rest I don't think one can look at the window and say we are not showing ambition. We spent about 6-7 million on a manager and director of football and are now fighting with Chelsea, Juventus and Napoli for players. Competing with those clubs off of the field was never going to be simple - it is not ALL about money. Our recent history works against us.
It's certainly not a dull period to support our club!
