Tottenham boss Harry Redknapp admits he doesn't know if Darren Bent and Roman Pavlyuchenko can be their long-term attack.

"Bent and Pavlyuchenko were £30million and that is a lot of money to spend on two strikers and then say they can't play together," Redknapp said.

"I'm left with that problem and whether they can, I don't know."

Even though Redknapp wants a striker, he will continue fielding Luka Modric in his free role.

"There is a shortage of quality players around the world and when you have one you have to keep hold of him and find a way of getting the best out of him," the Spurs boss added.
