Andre Villas-Boas tells Manchester United's new manager David Moyes to keep his eyes off Gareth Bale When asked if a change at Manchester United would help him to keep Bale, Villas-Boas said: "Probably. Obviously David will set up new targets. I'm pretty sure that whatever David does in the market will be excellent. But to get a player of Gareth's dimension is firstly not in our interests but also very difficult. I have those guarantees [that he will stay]. He is very driven to be successful but you can see that he is enjoying his football and all of the indications I have are that he will continue. It would be good for him [to sign a new deal], and I think he deserves it for the season he's had. Obviously we could put to bed every single speculation that's coming out, which we are calm about, and I think it would be a reward for what he has achieved this season. Tottenham will look to put pressure on north London rivals Arsenal, who are not in action until Tuesday, by moving back into the top four and opening a two-point gap if they beat Stoke City tomorrow . The game has extra significance as it will see Bale line up against Charlie Adam. Adam was branded a "coward" by Bale last year after a pre-season game in America when the Tottenham forward picked up an ankle injury and was forced to leave the field. It was not the first time Bale had been on the receiving end of a rash challenge from the Scotland international. Back in 2011 Adam, who was then playing for Blackpool, made a reckless challenge on the Welshman which forced him to spend three months on the sidelines with ankle ligament damage. Villas-Boas is confident, however, that there will be no repeat of the bad blood between the players. I would be surprised if it happened again. I don't think it will have an impact on Gareth. After the player [Adam] acknowledged he made a bad tackle, I'm sure it won't happen again.
