Manchester United boss Erik ten Hag has criticised the congested fixture schedule after Marcus Rashford picked up an injury against Everton.
Rashford laid on an assist for Anthony Martial to score Man United's second goal in a 2-0 win over the Toffees. He then pulled up with a suspected groin injury minutes later, and was replaced by Wout Weghorst in the 81st minute.
The England international has scored 27 goals and registered 10 assists in 47 appearances for the Red Devils across all competitions this season. Ten Hag was concerned by the injury Rashford sustained late on, and has blamed the fact that Man United played three games in six days.

"We have to wait and see what it is and how bad it is," Ten Hag told BT Sport. "It doesn't look well.
"We have to protect our players - everyone wants the best players on the pitch, everyone wants to see great, entertaining football like you see today, but then you need your best players."
He added: "I don't know [about Marcus]. It is like this when you have to play so many games in short notice, especially when the schedule is this tight. Players can't recover and you run the risk that players can get injured. You have to be aware of that.
"You can't say [exactly what has happened], even when you speak to him. We have to wait until tomorrow, or the day after tomorrow, then we will see what is the diagnosis."
