April 2 (Reuters) - Manchester United's England left back Luke Shaw will struggle to earn a place on the substitutes' bench and is a long way behind his rivals for a starting spot at his club, manager Jose Mourinho has said.
The 21-year-old, who suffered a broken leg last season, came on for England during last week's friendly in Germany but Mourinho has used him just twice in four months.
"I cannot compare the way he trains, the way he commits, the focus, the ambition. I cannot compare. He is a long way behind."
Shaw, who joined United for 27 million pounds ($33.87 million) in 2014 from Southampton, was left out of the squad for the 0-0 draw at home to West Bromwich Albion on Saturday.
Turning to his injury-hit squad, Mourinho said he was not sure if France midfielder Paul Pogba would be fit for Tuesday's Premier League game at home to Everton.
"Pogba I cannot say he is ready for Tuesday because I don't know," he said. "I think (Juan) Mata, (Phil) Jones and (Chris) Smalling (will be out) for a long time, but I don't think Pogba is such a long-term injury as the others."
Smalling, who has been wearing a leg brace, and Jones (toe)were injured on international duty with England, while Spaniard Mata has had surgery on a groin problem.
