MU and Amorim handed huge injury BOOST amid mounting pressure on their boss

Manchester United defender Lisandro Martinez is back on the grass in a huge injury boost for Ruben Amorim.

The Argentinian centre-half has been out of action since February, when he suffered a ruptured ACL during a Premier League game at Old Trafford against Crystal Palace.

He underwent successful surgery later that month, thereby marking the beginning of a long road to recovery.

Now, almost exactly seven months on, it seems Martinez is at last nearing a return to action as the 27-year-old shared a picture of him back out on the grass in his boots.

With the left-footer yet to take part in training with the first-team, Saturday's clash against Chelsea will however no-doubt come to soon for him, thought a return after the upcoming international break could be a realistic target.

News of Martinez's impending full recovery comes at a time where pressure is mounting on United boss Ruben Amorim following a poor start to his second season in charge.

After a promising performance against Arsenal on the opening day of the season, they drew at Fulham before suffering a disastrous loss at League Two minnows Grimsby Town. Then came a last-minute victory at Burnley, their first of the campaign, and later Sunday's 3-0 thumping at Manchester City.

Sitting fourteenth in the table, Amorim's side are yet to keep a clean sheet and have scored just one goal from open play in the Premier League.

The United boss however insisted he will not change his 3-4-3 system in the coming weeks post-match at the Etihad.

Amorim said: '‘I am not going to change. When I want to change my philosophy, I will change. If not, you have to change the man.

‘Losing faith in your ability to turn the situation around? No, that is not the way. I believe in my way and I am going to play my way until I want to change.

‘My message (to the fans) is that I am going to give everything, always thinking about what is best for the club. The rest is not my decision. Until I am here, I will do my best. I really want to win games.’

It's thought the Portuguese coach retains the backing of the Manchester United board and Sir Jim Ratcliffe for now, but if results don't improve that may well change.

It's understood some players have never been comfortable with the 3-4-3 system that was introduced when Amorim succeeded Erik ten Hag in mid-season last November.

United hoped that giving the 40-year-old a full pre-season to work with the squad, and £236million for new signings to fit his system, would see an upturn in results after the club's worst campaign in more than half a century.

The players are still struggling to get to grips with Amorim's style almost 11 months after he took over, and even one of his staunchest allies, captain Bruno Fernandes, is believed to be unhappy operating in a deeper midfield role.

United sources say it would be wrong to suggest that Amorim has lost the dressing-room, and insist he still has support among the squad.

But former United star Wayne Rooney has questioned whether the players understand the system, and claimed that United are going backwards under Amorim who has won just eight of his 31 Premier League games.

'We just watched it a lot of the lads who played the game today, and I don't think anyone can understand and comprehend what is going on,' said Rooney, who was in South Korea for a legends' game with some of his old United teammates.

'We are all watching it, and we all struggled to give what we see how Man United play. What are the patterns? What are we seeing what might improve the team moving forward? We have all played the game at the highest level and it is very difficult to see that.

'Speaking to Rio (Ferdinand), we want to support the team and the manager the best we can, but we also have to be honest as the fans are not fools.

'Rio was out with the team in Chicago pre-season. I go to the training ground a lot with my children, and it does put us in an uncomfortable position. But we have to be honest with what we're seeing. Frankly, it is not good enough.'
