Had a poor half, it happens.
Tielemans looked dodgy in his first few games for us remember.
Even Kamara has been caught in a similar way and cost us goals a few times.
Ah was just saying this myself regards players caught on the ball but to be fair it was very poor play that seen before from past midfielders but not what Onana acted. The way he went down and tried to win free kick that cost us the goal. The commentator Carragher suggested his pride and ego was hurt and was pretending to be injured which is actually quite a controversial statement.
We've seen Dendocker and Kamara, Tielemans and even great Douglas Luiz lose the ball when a player tight on them so it's a learning process.
I thought Barkley should have started the match instead of Onana and Emery was quite within his rights to haul him off at half time.
