Manchester United defender Luke Shaw has warned Zlatan Ibrahimovic and Marcos Rojo not to rush their recoveries as the pair begin their journey to come back from significant knee injuries.

Shaw, 21, broke his leg against PSV Eindhoven back in September 2015 and has struggled to regain full fitness since, with manager Jose Mourinho even questioning the left-back's commitment.

However, the defender had some sage advice for his more experienced teammates.

"One of the important things with these injuries is never to rush it," he told United Review. "I'm sure they will want to get back as soon as possible, but with the extent of the injury and how important it is to make sure it recovers well, so they can get back to fitness, staying positive, is going to be hard.

"But you look at the end goal and keep fighting every day, keep trying to get better and better, and push yourself.

"The support they've got from all of us and all of the fans is a key factor. I think everybody has to be together in these hard times when you get a long injury. They are two strong characters. I am sure they will get through it and come back even stronger."

United's players wore Ibrahimovic and Rojo t-shirts in a show of support before last weekend's 2-0 win at Burnley, which Shaw insists shows the team's unity.

"I think it was the manager's idea and it was a nice touch," Shaw added. "I know Marcos and Ibra will appreciate it. Obviously I know what they are going through now, it is going to be a long and hard road, but you couldn't have two stronger players in Marcos and Ibra.

"You have seen Zlatan's post on Instagram as well. He is very positive about his return and we all hope they fight back quickly, strongly and come back even better. I am sure they will.

"It's a really good [atmosphere at the club]. We have got a mix of experience and youth. The experienced ones are always there to help us, the likes of Wazza [Wayne Rooney], Youngy [Ashley Young], Carras [Michael Carrick] and Ibra. They all help if you need them and I have especially had a lot of help from Carras, which was nice in my situation.

"The togetherness is really strong in our squad, everyone is really close, gets on well and we all want the best for each other. We're all pushing for the same thing and that's to win trophies."
