Daniel James reportedly left his new teammates stunned by topping Manchester United's pre-season fitness tests.

The Wales international joined the Red Devils from Swansea City in a £15m deal last month.

James was part of the United squad that jetted out to Australia at the start of the week, and The Sun claims that he maxed out the bleep tests in one of the first training sessions down under.

"The word from Carrington is very encouraging on young James," an insider is quoted as saying. "He is clearly ahead of the game. He has topped all the early fitness charts. Ole was impressed with seeing him doing his own work.

"He came out top in the sprints, even the short ones, by a good margin of five or so yards. He did one fifty metre sprint that left teammates five metres behind him and also maxing out the bleep test."

James headed to Dubai for warm-weather training prior to linking up with United last week.
