Yes, very disappointing. Last 2 matches, when Coleman goes out, Lampard moves Iwobi to RB. I think Doucouré played there once or twice last season, maybe 20-30 minutes each time. As plaidharper says, Iwobi is easily our best ACM. Sure, he can play RB or RWB for a bit, but his great value is lost.
Put Doucouré there, in emergency, unless you think Coleman is an emergency from kickoff. I don’t, but he can’t play 90 minutes.
