Manchester United head coach Michael Carrick said he had to be "careful" with Mason Mount after the England midfielder handed United an injury scare in their friendly draw with Paris Saint-Germain.
Mount has had a torrid time with injuries since signing from Chelsea in a £55 million deal three years ago, starting only 25 Premier League games for United in that time.

The 27-year-old has been successfully deployed by Carrick in a central midfield role during preseason, leading to speculation that United may not make another expected signing in that department.
But Mount played only 18 minutes of Saturday's 1-1 draw against the European champions in Gothenburg before being replaced by Scotland international Tyler Fletcher.
