How are they going to raise more than €60m to be able to go for Eze? There's only few weeks left and none of their players are in any serious transfer negotiations. Arsenal are usually bad at selling and clubs barely come for their players. The Eze deal is completely off if it means that they must sell to buy.
Trossard is not going anywhere, Jesus is injured no one is coming for him, Martinelli no one is coming for him as well as it stands. Who are they going to sell?
I don't think that money would be a problem at all. If you check, they've only spent a bit more than half of what Liverpool has spent so far this season. Though Liverpool made a couple of sales which isn't even up to half of what they spent. But Arsenal's problem has always been their difficulty in capitalizing and making decisions in the transfer market. Their record sale was Chamberlain, which was a €38m deal, which doesn't tell good of a supposed big club.
But I think this current sporting director (Berta), can do a better job. He is very rigid with asking prices. That was why they couldn't get Sekso despite Arteta prioritizing him. Arsenal really have a lot to do aside winning trophies.
