I can see the logic in signing Wellbeck on a free if we end up selling one or both of Niasse and Tosun.
So say he is just as crap as Niasse (despite spending his entire career at United and Arsenal), we will get about 12 million for Niasse and about 20 million for Tosun. So 32 million pound in the bank and we'd have replaced our back up strikers with another back up striker, but for free.
Giroud and Sturridge are also available on free transfers next summer.
It's all well and good demanding a top class striker, but they are in short supply, and will probably cost more than what Moshiri paid to buy the whole of Everton.
