​Jose Mourinho has never been the most approachable or agreeable of chaps, and it seems that his latest feud involves Championship club Wolves. 

The Manchester United manager has reportedly blocked an emergency approach for young goalkeeper Sam Johnstone from the Midlands club.

Wolves have found themselves in a desperate situation, after their two first team goalkeepers were both put on the injury list, ahead of their Tuesday clash against Cardiff in the Championship.

The injury-stricken club put in a bid for an emergency one-week loan for Johnstone, as is allowed outside normal transfer window regulations in extreme circumstances.

However, Mourinho has refused to allow the 23-year-old to move even for seven days, according to the ​Telegraph

The petty situation has reportedly arisen because of Wolves manager Paul Lambert's decision to restrict Cameron Borthwick-Jackson's playing time at the club. Another United loanee Borthwick-Jackson was farmed out to Wolves in the summer in the hope of getting game time and developing in league football.

The young defender has only made seven appearances for Wolves since the loan move, and is set for an Old Trafford return in January, after Lambert failed to play him even once.

Johnstone will instead be loaned out to Aston Villa for the rest of the season, with former United defender Steve Bruce in advanced talks to bring the goalkeeper in to help Villa strive for the Championship play-offs.

Villa are also likely to ease Carl Jenkinson's struggles at Arsenal by snapping him up on loan in January. The right-back failed to impress after Hector Bellerin's injury afforded him a chance in the first team.
