While he admitted scouting Eden Hazard, the United supremo still feels his close season business gives him more options over the course of a season.
He said: “Chelsea have changed and without Drogba they have another way of playing and it’s been successful because they are top and undefeated.
“When I first saw them playing Oscar, Mata and Hazard in the same team I thought that was a risk.
“But they give real problems for defenders. If you contain the three in the middle of the park then you’ve got a chance but that’s not certain.
“We’ve brought Van Persie and Kagawa and it means that my adaptability is better. The unpredictability is better so I think that may help us.”
