Manchester United veteran Ashley Young is convinced by the potential of their attacking pair Romelu Lukaku and Alexis Sanchez.

Alexis provided an assist for one of Lukaku's two goals in their FA Cup win over Huddersfield Town.

"When you have a striker scoring goals...his hold-up play, his all round game was fantastic and he's done that all throughout the season," said Young of Lukaku. "He's getting goals and to get two today was brilliant for him.

"When you've got someone who can hold up the ball like he can and get in the box it's fantastic.

"You can see the combinations between them. Alexis comes inside and Rom's seen him and picked him up as well and they're picking each other out and they have worked well together so far."
