The England man claims he and his one-time West Ham teammate share an "unwritten agreement" at the business end of the season and insists there "is not really any dialogue"
Manchester United defender Rio Ferdinand has ceased all communication with long-time friend and Chelsea star Frank Lampard as the two sides prepare to clash in what could prove a title decider on Sunday.
The two players were teammates at West Ham in the past and remain England colleagues although Ferdinand admits the duo share an "unwritten agreement" that they do not talk to each other at the business end of the season.
"At this time of the season, me and Frank don't really talk," Ferdinand told reporters on Friday.
"It's an unwritten agreement between us. During the season we will send each other the odd text here and there but when it comes to the business end, if we are both involved in the title race, there is not really any dialogue."
With United closing on an unprecedented 19th title, Ferdinand admits that the players are focused on simply winning the league rather than overtaking Liverpool to set a new record.
"At the beginning of the season everybody was tipping either us or Chelsea to win the league," Ferdinand added.
"Arsenal made a good go of it but have fallen away. Even after Sunday, there are still two more big games to come, so I don't think it will decide the season. But it will have a big say in where the title goes.
"The thought of winning 19 titles is not going to be the overriding factor as far as the players are concerned. We just want to win the league.
"There are players at the club who have not won a league title yet and there are others who have won quite a few, like Ryan Giggs and Paul Scholes. We are all at different parts of the spectrum but hunger to be successful is exactly the same.
"We do understand what it means to the fans but if we get involved in thinking about things like that it isn't going to help us."
United will go into the game with the knowledge that it beats Chelsea over two legs in the Champions League quarterfinal, which Ferdinand believes gives his team a slight boost.
"I am not sure it proves we know how to beat them and I don't know whether it will play on their minds, but it lets them know we are capable of winning," he continued.
"We played particularly well over the two legs and we are confident."
