The winger signed a contract extension in the summer, keeping him at the clubWhite Hart Lane until 2016. However, this has not stopped mounting speculation that Bale will move to one of the two La Liga giants next summer.
But Laudrup, himself a former Barcelona and Real Madrid player, has told Bale to think carefully about the next step in his career. He told reporters:
“As a top player, when you have a possibility to go to the other teams, it’s very important to think what would be best and where would I fit in.
“You have to realise that playing in Barcelona and Madrid is completely different to playing in the Premier League.
“The football is totally different. There is no space to play. Everybody defends with 10 against you, in the last third of the pitch, home or away.
“There is nowhere to run, so that part of his play would have to go away in a lot of games.
“Everything is one-touch and move.”
Bale's reputation in Europe grew in 2010, when Tottenham finally achieved fourth spot under former manager Harry Redknapp. Following impressive displays against Inter, FC Twente and AC Milan two years ago, Bale's ability has continued to grow as he terrorises defences and tries to baffle goalkeepers.
However, Laudrup recognises that a move to Real Madrid for the Wales international will mean he is unlikely to play on the left-wing.
He continued: “If you go to Real Madrid, you have to say ‘what is my favourite position?’
“If it is on the left, that is where Ronaldo plays. So where would Bale play?”
Bale is, however, unlikely to face Laudrup's side on Sunday when Spurs and Swansea meet, remaining on the sidelines following a hamstring injury he picked up in Tottenham's 3-0 win at Fulham.
