Jesse Lingard says Manchester United's players are in daily contact with the club's fitness coach through WhatsApp.
Players are having to train by themselves at home during the coronavirus pandemic.
"We have a WhatsApp group with the fitness coach," he told Sky Sports.
"He's giving us daily fitness plans to do all week, so we're all keeping active.
"We're in contact with the manager and the coaching staff, seeing how they're getting on, so we're still a tight-knit group."
