With Deadline Day fast approaching, Manchester United only have one major signing confirmed so far.While the Red Devils have since completed moves for Diogo Dalot and Lee Grant, they made their biggest move early on with the arrival of Fred for an undisclosed fee.He arrived at the club as a replacement for Michael Carrick and has recently linked with up the United squad after a World Cup campaign with Brazil.Fred made his first start for the club against Real Madrid, impressing supporters in the process, and was handed a major opportunity to impress in Sunday's friendly against Bayern Munich.With the Premier League getting underway this week, Jose Mourinho could form a strong opinion on his starting XI from what he sees at the Allianz Arena.

Man Utd vs Bayern Munich

Not only that, but Bayern played a strong side to ensure their visitors would be well and truly tested.

The likes of Manuel Neuer, Mats Hummels, Thiago Alcantara, Arjen Robben, Thomas Muller and Frank Ribery all took to the field in Bavaria.

As a result, Fred had plenty to deal with in midfield and even with a friendly fixture lacking that extra edge of competitiveness, it would be a truly telling fixture ahead of the season proper.

And United fans quickly started to form an opinion about their Brazilian midfielder on social media.

It's important to confirm that that was Fred, too, because supporters were taken aback by his partnership with comp tract Andreas Pereira who has enjoyed an impressive pre-season.

Some fans are also rather excited to see how the pair would fare alongside Paul Pogba.

In other words, Fred was getting rave reviews - check out the pick of the tweets below:

Criticise Mourinho's transfer business as much as you like, but at least the Portuguese has made his most expensive deal count and he looks an enviable midfield addition for the club.

Nevertheless, there was certainly frustration as far as the overall team was concerned in Bavaria.

United have enjoyed a frustrating pre-season - barring the victory over Real Madrid - and rumours surrounding Mourinho suggest unrest going into his third campaign as manager.

There is undoubted pressure on the the Portuguese to deliver the club's first Premier League title challenge since Sir Alex Ferguson's retirement and close the gap to Manchester City.

Fans aren't feeling all that confident but pre-season suggests that, whatever happens, Fred could play a crucial role going forward.
