Marcus Rashford sparks injury concern after his latest post on his fitness

With a cryptic Instagram post, MARCUS RASHFORD has raised questions about injuries.

Last night, the Manchester United star played in the Europa League matchup between his team and Barcelona.

The team led by Erik ten Hag staged an inspiring comeback to win 2-1 on the night and 3-2 overall.

However, Rashford's evening came to a disappointing end when he was replaced in the 88th minute and showed signs of discomfort.

After speaking with Ten Hag, the red-hot forward took off his left boot and went straight down the tunnel.

He used Instagram after the game, but not just to post about winning.

As an alternative, he uploaded a photo of himself carrying his boot as he walked away and added an emoji of a bandage.

United supporters are concerned that Rashford might miss Sunday's Carabao Cup final against Newcastle as a result of Rashford's post.

After the game, Rashford posted the following tweet:“What a night for the team! Next stop Wembley.”

Since the World Cup, the England star has been in sensational form, scoring 17 goals in 20 games since his return from Qatar.
