Ole Gunnar Solskjaer says Odion Ighalo is "doing what it says on the tin" after the Manchester United striker scored twice against Derby.
Ighalo notched a brace as United booked their place in the quarter-finals on the FA Cup with a 3-0 victory over Wayne Rooney and co. on Thursday.
The Nigeria international has now scored three goals in six appearances for Solskjaer's side since moving to Old Trafford in January.
"[Ighalo] is doing what it says on the tin. He's come in and he's playing up front, a different type of striker," he said.
"He gets chances every game. Today [he] could have had another couple. [I'm] happy with him. Gives us a chance when Mason [Greenwood] and Anthony [Martial] can be kept fresh."
"It doesn't hurt [living the dream] but he's here on merit, he's here because he is a goalscorer and a different type of striker for us," he told Sky Sports.
"We might get to the summer and think we want to extend this, who knows?
"He's come in as a breath of fresh air as well. He had chances in his five minutes against Chelsea, he scored against Brugge, he had chances against Watford, he had a very good save [from a shot] against Everton - there have been good saves, he doesn't miss the target very often.
"Even for Anthony, Mason and Marcus [Rashford] to learn that it is where the sharks are swimming. It's comfortable outside the box and you can have a few shots. It's in there where it might be a bit tougher and you might get hurt - that's where you get goals."
