He added: "At the moment we are more worried about building a greater distance to Arsenal, who are fifth. That is our ultimate objective.
"If we can open that gap further it will help us over the last nine games, but we don't worry too much about second."
Both sides have been accused of being over-reliant on their top scorers and have even been called one-man teams. Spurs' former-Liverpool goalkeeper Brad Friedel denies that is the case, at least with Bale at White Hart Lane.
"That's ridiculous - that's a poor comment," he said.
"Gareth is an exceptional player and we have a lot of exceptional players.
"Every good team has their star players. Gareth is playing well for us. We are a better team for it, but we have some exceptional players that can step in and do the job."
