Diogo Dalot wants playing guarantees before signing a new deal with Manchester United.
Sport says Dalot has revealed the one condition that must be met if he is to sign a new contract at Old Trafford.
The Portuguese defender has been revived under Ten Hag this season but there is the concern that he will not stay on in Manchester beyond this season after his deal expires next summer.
Dalot has stated that he is willing to sign a contract extension if he is guaranteed a starting spot next season.
With United looking to bring in a new right-back, they may face losing out on the 23-year-old as a result.
