I'd put him as a 10 yeah. Bernard is injured and I don't think Walcott can keep up his form so our only proper wingers are Iwobi and Richy. If Bernard was fit it would be completely different but since he's not, Siggy has to play.
He's played relatively poorly this season but today is a must start for Siggy. Spurs shouldn't play deep like most teams have against us this season and he could do some real damage similar to the end of last season
Have they confirmed anything regarding the capacity this evening? Stadium looks absolutely stunning though and it's definitely pretty unique with the waterside setting
