Manchester United coach, Jose Mourinho, has asked the club's players on holidays to cut short their vacation.
Some of the key players, including Romelu Lukaku, Paul Pogba and Jesse Lingard, have not resumed for pre-season tour, following their national teams' prolonged participation at the 2018 World Cup.
Though the players are entitled to prolonged break for adequate rest ahead of the 2018/2019 season, but Mourinho has appealed to their sense of fight.
“I hope that the boys on deserved holidays take care of themselves a bit and that somebody wants to do what Rashford and Phil Jones decided to do, which is to be back a bit earlier to try to help the team because for the beginning of the season we are going to be in trouble," Mourinho said.
The Portuguese has expressed dissatisfaction with the quality of first team players at his disposal in the International Champions Cup, ICC, in the United States. He has also lamented the club's lack of activity in the transfer market, hence pessimistic about United's challenge for any silverware next season.
According to Daily Mail, with Liverpool setting the pace in the market, the relationship between Mourinho and United's executive vice-chairman, Ed Woodward, has been fractured, reaching "boiling point."
Alexis Sanchez is the only striker available to Mourinho in the U.S, and want-away striker, Antonio Martial is yet to return from the birth of his child with his girlfriend.
New signing, Fred, made his debut in Sunday's 4-1 friendly defeat to Liverpool in the ICC, although new right-back, Diogo Dalot, is still suffering an injury setback.
Nemanja Matic is the latest name added to United's list of injured absentees, which includes Antonio Valencia, Chris Smalling and Marcos Rojo.
The club have been left frustrated over the pursuit of Leicester City defender, Harry Maguire, who would likely face Manchester United in the new Premier League season opener in less than two weeks time.
