Redknapp and Tottenham Hotspur remain keen to hang on to Modric, whose team-mates thumped Hearts 5-0 in the first leg of their Europa League play-off on Thursday night. Yet even if Chelsea's overtures for the midfielder are ultimately successful, Van der Vaart says Spurs can still challenge at the top of the Premier League.
"We still have Niko Kranjcar, Jake Livermore, we have fantastic players," Van der Vaart said. "We don't know, it's a lot of speculation and I hope he's going to stay, but if he leaves then Kranjcar is a fantastic player and he's a little bit like Luka, he can play there. We have a good squad and when we play like we did against Hearts, we know we can win against everybody."
The lack of incoming transfers at White Hart Lane does not trouble the Dutchman. "We have a good team," Van der Vaart said. "Of course, maybe you need a few players but nobody has left so that's a good thing. If we play like last season we'll be successful. Manchester City, in particular, have spent a lot, United also, but we are different. It's not a problem. We have a good squad and I think we can do something."
The Spurs centre-back Michael Dawson is similarly confident, albeit hopeful the club can retain the services of Modric. "You want to keep your best players," Dawson said. "It is as simple as that. I have said it before and the chairman has come out and said he is not selling. The lads certainly want him to stay."
Dawson would welcome the potential arrival of Emmanuel Adebayor from Manchester City, with the England international more keen than Van der Vaart for new blood. "He is a top player and whoever comes in is always going to improve the squad. If you want to do well, you can't have enough quality. A couple of additions would help us this season to freshen things up. You have always got to bring players in."
Next for Spurs is a trip to Old Trafford on Monday night, the opening match of the north London team's Premier League season. The straightforward win in Edinburgh has boosted confidence levels in Redknapp's squad.
"I don't think we will be undercooked against United," Dawson said. "Of course, it will be a very different game on Monday night and obviously a lot tougher [than Hearts] but at least we're going into it with a competitive game under our belts.
"Whoever the opposition, you'll always feel good about yourselves going into a game having scored five in the last one. We have not got a great record at Old Trafford but there is still belief we can go there and get something. Our performances have been decent but unfortunately we have not always got the results we warranted. It is a tough place to go but we are ready."
