Andre Onana started the season well, and at one stage had the best data (saves vs expected saves) of any keeper in the top European leagues. Yet, he has made some ridiculous errors in recent weeks against Wolves, Forest and Brighton.

Can United afford to dip into the market? Ed and Dominic discuss.
