Jose Mourinho has hailed Luke Shaw as one of the best left-backs in the world and challenged him to maintain his current form.

Shaw, out of favour for much of Mourinho's reign, has started Manchester United's last five games and is likely to keep his place for tomorrow's trip to Burnley.

Mourinho heaped praise on Shaw and said the 22-year-old must not allow himself to drop back into the bad old ways that made him a peripheral figure for so long at United.

"He's played very well," said Mourinho.

"He was already improving and playing well when I start playing him after that long spell without minutes.

"I remember the first time, in the Champions League, he was coming step by step.

"And now with a good run of matches and continuity also, playing like he did against Everton, two days after a previous match, he's good, solid, physically much better, mentally much stronger, tactically understanding the game much better and what we need in different phases and circumstances.

"I'm really happy and [looking at the transfer market], I can say that in this moment I don't see many left-backs better than this Luke Shaw."
