He said: “One of the most important things for Manchester United is that Rasmus Hojlund keeps improving. I watched him last season and at the Euros and was a little bit concerned about his level of finishing, but I thought it steadily improved.
“I still don't think he's anything like the finished article and I don't think he will be for at least two or three seasons.
“However, from United's point of view, there has to be a steady improvement in him, and Erik ten Hag will have to rest him at times as well.”
