Manchester United boss Erik ten Hag admits he has concerns about David de Gea's kicking.
There has long been question marks over his distribution from the back.
They were raised again on Tuesday when he gave the ball away almost leading to a second Real Betis goal.
Speaking after the game Ten Hag said: From today I can't ignore it, but I think we have seen many games he did really well.
We work on that but David is working on that.
But I think we have seen in this season that he is improving and he will keep improving, I'm sure.
I don't know what the reason today was. There was a lot of wind, a different ball, probably he had some problems with that, but I know we can deal with it and he will do better Sunday."
De Gea is still to agree on a new contract with his current United deal running out at the end of the season.
