I'd say 100% that Lennon and Oumar is off and Walcott will cover both of those losses imo
I wouldn't loan Lookman out either, him, Vlasic, Bolasie and Walcott would give us really nice options for both wings plus the majority of them can play through the middle if need be.
I'm not a huge Walcott fan as he flatters to deceive but what he does have is pace and can finish and that gets us up the pitch quicker and makes us more of a threat. So if Lennon and Oumar goes and Walcott comes in return I'll take that.
Only thing is mate we have one game a week from now on.
I'd be happy to keep them but our squad needs some serious trimming.
