Center Back: Chris Smalling-
The 6-year-old towering defender has been one of the great performers alongside De Gea in the side. His defensive prowess took United to a different level defensively. He does need to improve his heading abilities, but otherwise, the player has been one of the positives for Manchester United this season.
His tough tackling ability and quick reaction helped his team a lot this term and even if the new manager comes, he will retain his position at the back.
Center back: Rafael Varane-
The French defender has been linked with Manchester United for so long now, and it won’t be a surprise to see him in the Red’s shirt in coming years. He missed out many games this year for Real Madrid through injury, but the 23-year-old French international has shown the entire world what he is capable of.
His techniques both on and off the ball is brilliant. He positions himself well and that allows him to intercept the ball very easily from the opposition’s player. At this very young age, the towering defender has a fit and muscular body and through that, he can easily take on the English attackers.
Left Back: Luke Shaw-
The 20-year-old English full back missed the entire season due to his injury he picked up against PSV in the Champions League draw. The former Southampton man is a quick and very agile full back who knows everything about playing in the premier league.
Shaw has the tendency to play an attacking brand of football, and being a quick sprinter, he makes life difficult for his opponents. His decision making and defensive skills are world class and that makes him the prior man in our list for the mentioned position.
