Louis Saha insists that Manchester United’s glittering array of attacking options need to stop 'over-thinking' to fire themselves back to form.

United beat Villarreal 2-0 on Tuesday night to seal their place in the last-16 of the Champions League, in their first match since Ole Gunnar Solskjaer’s departure.

Cristiano Ronaldo was the focal point of their attack, flanked by Anthony Martial and Jadon Sancho, Donny van de Beek was also included in caretaker boss Michael Carrick’s starting line-up.

United also brought both Marcus Rashford and Bruno Fernandes off the bench, while Edinson Cavani and Mason Greenwood missed out due to injury. Yet, despite their embarrassment of riches, United's attack has struggled to click into gear this season.

Former United striker Saha — who won two titles during his time under Sir Alex Ferguson at Old Trafford — is confident the club’s enviable forward line can get them back to winning ways.

"Because the Premier League is a marathon, I still believe they can pick up form and go on a run," Saha told 101greatgoals.com.

"And when they do, they will be unstoppable because those front four players are one of the best in the Premier League. Of course, they will need to defend and ensure there’s the right balance.

"But when they eventually find the right formula and things click – especially in their heads where at the minute there’s too much over thinking – those players are unstoppable when they play naturally.

Saha also paid tribute to French forward Martial, who has been a peripheral figure this season, since the arrivals of Ronaldo and Sancho.

On his fellow countryman, the Frenchman added: "Martial, when he’s on top form, he is unplayable. Put them all in the right position and conditions and they’ll fly. But it comes back to humility and mindset.

"I’m sure they’re confident guys but they need to have the mindset of doing the things they don’t like to work hard for the team."

United, who are currently eighth in the Premier League table return to domestic action when they travel to Stamford Bridge to face leaders Chelsea on Sunday.
