He said: “This is definitely the strongest squad I have been involved at United.
“There are more players and better quality players as well. The competition for places next season will be huge.
“All the players are excited by the new arrivals. I know all about Owen Hargreaves from England, while I am sure Nani and Anderson will do well for us. Everyone is going to have to be on top of their game and try their best to get into the team.”
