Fans go into meltdown after spotting shock player travelling with first-team squad ahead of Man Utd vs Arsenal

Fans have been reacting on social media after spotting a surprise player travelling with the first team squad ahead of Manchester United's match against Arsenal.

On Sunday afternoon, two of England's biggest clubs will go head-to-head as United welcome Arsenal to Old Trafford for a mouth-watering Premier League tie.

Mikel Arteta's men will be looking to secure a victory in their bid to chase down Liverpool in the title race. The Reds won 3-1 against Southampton on Saturday, meaning their lead currently stands at 16 points.

Meanwhile, United will want to end their horrible form after a disappointing 1-1 draw against Real Sociedad on Thursday night.

Heading into the match, both teams have been hit with multiple injuries.

However, a video has gone viral on social media, which could be a big boost for Arsenal.

Brazilian winger Gabriel Martinelli was spotted travelling with the Arsenal squad as they were filmed arriving at Manchester.

Martinelli suffered a hamstring injury last month and, at the time, was projected to be back around mid-March.

Reacting on social media, one fan said: "Probably be on the bench, 10 mins today, 30 mins v PSV then back for Chelsea maybe."

Another tweeted: "Put the Champions League and the Premier League in the bag."

A third fan added: "A suprise start for GM11 would feed families .. Could do with the pace in behind."

Someone else wrote: "Probably won’t play but atleast he’s close."

A fifth commented: "My boy is back."

Speaking ahead of the match, Gunners boss Arteta said: "We need to look at threats from all areas. We lost very important wingers that were providing a lot for us in that final third and we’re looking to explore other options as well.

"The team has this capacity to adapt, we have a lot of players with great football intelligence to understand when to move and why, especially to do certain things. The other day certainly flowed and we saw actions and combinations that are very difficult to defend."
