LONDON, July 7 (Xinhua) -- There were five players missing when Manchester United returned for pre-season training on Monday after the club has given them more time off to try and seal a move elsewhere.

Jadon Sancho, Antony, Marcus Rashford and Tyrell Malacia are not in Ruben Amorim's plans, while Alejandro Garnacho has asked to leave due to his poor relationship with the head coach.

Sancho spent last season on loan with Chelsea, but the south London club opted against signing him on a permanent basis, even paying a penalty clause of five million pounds (6.8 million U.S. dollars) for rejecting that option.

Juventus is thought to be interested in Sancho, with United asking for around 25 million pounds for the winger.

Antony had a successful second half to the season on loan at Real Betis, and was a key factor as the club finished sixth in La Liga and reached the UEFA Conference League final, losing to Chelsea.

Betis would like to sign Antony again and the player has said he wants to return to the south of Spain, but the club's finances and Antony's high price will make it difficult to turn the loan into a permanent deal.

Como and Bayer Leverkusen are also thought to be interested in Antony.

Rashford also had a moderately successful loan with Aston Villa, which was cut short by injury towards the end of last season. The England forward has been linked with interest from FC Barcelona, who is still looking to sign a winger after its failure to sign Athletic Bilbao's Nico Williams.

Chelsea was thought to be interested in Garnacho, who asked to leave after being left out of the starting 11 in the Europa League final, but Chelsea has since signed Jamie Gittens and Joao Pedro, reducing the possibility of signing more forwards. ■
