Should Man Utd have signed Kepa?

BBC chief football news reporter Simon Stone has been answering your questions.

David asked: With Kepa Arrizabalaga having been available, should Manchester United have signed him? He has got to be a better option than Andre Onana.

Simon answered: First, we cannot be certain he wanted to make the move. Arsenal have more to aim for than Manchester United. Kepa might believe he can get into Mikel Arteta's team ahead of David Raya and, geographically, he can stay where he is.

As a goalkeeper, he might also think playing for United is setting himself up for a fall because he is exposed too often. It is true Onana has made mistakes - but he has also made a lot of good saves. The more any goalkeeper has to do, the more errors they make.

I accept doubts persist over Onana but, a bit like David de Gea - who was also heavily criticised in the end - my belief is there are more fundamental issues to address.

If United had a defence that was secure in possession and a midfield that could screen, then we would know how good the goalkeeper was. Just now, we don't.

Luke asked: Is it looking ominous for Manchester United? So much talk about giving Ruben Amorim a summer transfer window, yet we have managed to sign one first-team player so far and have not been able to sell our unwanted contracted players. Meanwhile, most other teams have strengthened their squads. Uh oh.

Simon answered: You can look at this situation in two ways. You are clearly correct - it is only one signing and obviously the five unwanted players remain. That is not ideal.

However, the way the five have been treated suggests Amorim is being allowed to make the decisions he chooses, which is clearly a positive - and the reality is no manager gets all the players they want as quickly as they want them.

United want to strengthen but they need to balance the books. At this stage, it is a question of trust. Admittedly, that is in short supply when it comes to United and their transfer dealings in recent summers.
