I get what you're saying about us being short in the squad. Just had a look at his profile. For some reason I thought he was very similar in style to Borini although from a more central position. With Borini available to cover that position if necessary, behind Defoe and Khazri. I'll backtrack on what I said about not needing him, especially with some of the injuries we have at the minute
However I do still think he's too delicate for the PL. The league now is the fastest its ever been. The games at the weekend were non-stop fast and exhilarating to the very last minute! Giacc's last 3 injuries were all ankle injuries which kept him out for most of his last season. I just don't think he can cut it long term. But yes, I'll concede your point about having him back for the last 12 games or so.
You have to wonder though, if Sam had the option of bringing him back during the window, why he chose not to.
