The loan-signing grabbed his first goal for the club in the 5-0 victory.
But it is the attributes Ighalo offers that pleases Solskjaer.
He said: "He plays up front, he can play with his back to goal and the goal was a good example of what you want of him.
"He can hold up the ball and he is what we have been lacking a little bit. If we hadn't had Odion tonight then Mason Greenwood would have had to play and we have a game on Sunday and that would put us in a tired position. We knew what we got when we signed him."
