Former Manchester United manager, Alex Ferguson has warned current boss Ole Gunnar Solskjaer that football is a result industry.
According to Ferguson, if Solskjaer does not get results, questions will be asked.
He, however, praised the Norwegian for putting his faith in youngsters at Old Trafford.
In an interview with the BBC on Thursday, Ferguson who was in charge when Solskjaer played for the Red Devils, said: "He had a will that he wanted to be a manager, and at a club like Manchester United, it's a result industry, without question.
"If you don't get results there's questions to be asked. He is getting the results, he really has done very well."
