TBF to the guy he was called offside so many times that he probably was sure this situation was offside too (and I dont really know the truth here, probably would be ruled out with VAR anyway). Once he realised the ref didnt give offside he lost all his confidence - he knew he looked like a clown there, nothing to really worry about, we always knew he is weak mentally. Hopefully he keeps his head up and continue the good form, I think of him as guy who could be ruined by episode like this unfortunately.
