Wayne Rooney admits it may take time before the fans of Manchester United see the best of new signing Juan Mata from Chelsea. Mata was the highest-profile transfer during January, moving north for £37.1m.
"It's exciting.
"Juan has come in and it's another world-class player to have in the squad.
"It'll take time, it can always take a little bit of time for every player to gel and to bond but we really hope we can all start scoring goals and help the team be successful."
