Manchester United goalkeeper David De Gea believes teammates Memphis Depay is on the verge of rediscovering his best form.

Depay scored the opening goal in the Red Devils' 2-1 win over Watford on the weekend and will be eager to impress against his former club PSV Eindhoven in Wednesday's Champions League clash at Old Trafford.

"[Depay] has had a tough few weeks and I'm sure he'll soon be back at the top of his game," De Gea told MUTV.

"He's going to bring a lot to the team and I'm sure he'll be really up for playing against his old club.

"We know it will be a difficult game but we need to get the victory and grab the three points."
