Rio Ferdinand has hit back at Chelsea manager Jose Mourinho after the Portuguese criticized the caliber of Manchester United's title-winning team.
Mourinho claimed neither United nor Manchester City had been "extraordinary" champions in the past two seasons.
"That was his first sound bite of the season, wasn't it? I think we expected it," Ferdinand said of the Chelsea manager's comments.
"I'm looking forward to Chelsea. We are really looking forward to it. Now we can start playing for something."
United's credentials were questioned before the start of the campaign following a string of unconvincing preseason results but David Moyes' side launched its defense of the title with a 4-1 victory at Swansea City on Saturday.
"We are professional people and want to win. You don't appreciate it when people don't put you in the position you should be," Ferdinand said. "Being champions you warrant maybe a little bit more but every next person is tipping someone else to win the league and putting us in third or fourth place.
"It seemed people thought we should have come away with zero points and there would have been a lot of noise if we'd lost. The vibe all week was people wanted it.
"So it was nice to go there – especially in the gaffer's first real competitive game – and to win convincingly – as we did."
