Senne Lammens has cut his holiday short to return to training with Manchester United ahead of the new season, sources have told ESPN.

Lammens was due to report back to Carrington on Monday but has chosen to return on Thursday, four days early. The goalkeeper is keen to get back to club football after the World Cup and build on his successful first season at Old Trafford. The 24-year-old was granted an extended break after being part of the Belgium squad this summer. He asked to come back early to ensure he's ready for the Premier League campaign when Michael Carrick's side face Hull City on Aug. 22.

Summer signing Youri Tielemans also reported to Carrington on Thursday, though his return was pre-agreed following his £35 million ($47m) move from Aston Villa. United's next fixtures include matches against Atlético Madrid, Paris Saint-Germain, Leeds United, and Milan.
