Anthony Martial and Marcus Rashford of Manchester United skipped training in advance of their pivotal Champions League match.

The Red Devils’ final opportunity to play in Europe this season is on Tuesday night against Bayern Munich.

Rashford entered the game in the 79th minute after replacing Martial at the beginning of Saturday’s 3-0 loss to Bournemouth.

But as football writer Simon Peach noted, the two forwards missed Monday’s Carrington training session owing to illness.

If the Red Devils are to have any hope of making it to the knockout stages, they have to be fully prepared and ready to go when they take on Bayern Munich.

Erik ten Hag is optimistic that his team can make up for their earlier-season 4-3 loss to Bayern.

He declared: “We played really well at several points in the game.

“That game went end-to-end for a considerable amount of time, but we also made several mistakes that were completely preventable.

“You have to give it your all while playing Bayern Munich because they have a very strong team and individual players.

“But as I say, Chelsea also amazing players, we dominate them and I think we can do it against Bayern as well.”

Last week, Man United defeated Chelsea owing to two goals from Scott McTominay.

The 26-year-old was sick and missed Man United’s Friday training session.

Although Rashford was the team’s top scorer the previous season, he has generally struggled with form this time around.

After 14 games, the forward has only managed two goals in the Premier League.

Martial, meantime, has dropped down the ranks at United and, barring a January trade, is expected to depart Old Trafford as a free agent at the end of the current campaign.

This season, the Frenchman has also failed to reach the back of the net, managing just one goal in 13 Premier League games.
