Ole Gunnar Solskjaer will warn Manchester United to watch out for Jack Grealish when they face Aston Villa on Thursday night.
The Villa skipper has been strongly linked with a move to United at the end of the season, particularly if Dean Smith's side lose their battle against relegation from the Premier League.
Solskjaer knows that Grealish is likely to be Villa's danger man, having scored when the two clubs drew 2-2 at Old Trafford in December, and will take steps to keep him quiet this time.
'I think the last game they caused us some problems, Grealish off left and El Ghazi on the right,' said Solskjaer.
