Ten Hag 'desperately needs Ugarte to be a success'published at 16:43 2 September
BBC Sport's chief football writer Phil McNulty has been answering your questions.
Sean asked: Looking at yesterday's Manchester United v Liverpool match, do you think it is far too early for Mainoo? Great potential, but I thought he was exposed yesterday and potentially targeted as a weak point in that midfield. Why they sold McTominay is beyond me. I think he was responsible for 12 points last season.
Phil answered: Kobbie Mainoo was exposed yesterday but he was in a tough position because Casemiro had such a nightmare before being replaced by youngster Toby Collyer.
Mainoo just had too much to do against a very good Liverpool side. I do not think he was the specific weak point. I think there was a lot of weak points all around him and I still think he will be a big player for Manchester United this season.
It was sad to see McTominay go but he has clearly been sold to ensure funds to buy Manuel Ugarte from Paris Saint-Germain. There is an awful lot riding on that deal for manager Erik ten Hag as he desperately needs Ugarte to be a success and make a difference.
