boss has been warned that teams will try to expose his £50m target .
Ten Hag has identified Inter Milan goalkeeper Onana as his top choice to replace David de Gea at Old Trafford.
De Gea in which he made more than 500 appearances for the club.
United have and are ready to return with an improved offer after Inter Milan rejected their first bid.
Ten Hag managed the 27-year-old at Ajax and believes he is the right goalkeeper to take the team forward following De Gea’s departure.
Ex-Ireland striker Tony Cascarino says Onana ‘appears a sensible choice’ but has highlighted one concern over the Cameroon international.
‘De Gea’s potential successor, Inter Milan’s Andre Onana, appears a sensible choice,’ he told .
‘He is outstanding with his feet and spent five years playing under Ten Hag at Ajax. However, he is not the strongest, and imposing teams such as Brentford and Newcastle United would test him with deep crosses.
‘He has the same questions to answer as De Gea did 12 years ago. United have come full circle.’
Manchester United legend , telling his YouTube channel last week: ‘He will give United more confidence and more ability to play out from the back and I think he suits and Erik ten Hag team.
‘He’s a real modern day goalkeeper. You see teams pressing him and he doesn’t even panic.
‘He gets the ball in, brings on the press says ‘come on, come to me’ and when that player comes to him he knows there’s a player free somewhere else and he normally finds them.
‘I think there will be mistakes and playing that risky way you do have mistakes and that happens, but it’s about staying true to your beliefs, finding the right balance and remaining calm throughout those periods.
‘I believe this is a deal that will be made at some point in the transfer window.’
