Rafael van der Vaart is on the brink of joining Tottenham Hotspur, but it remains unclear whether he was signed before Tuesday's transfer deadline, dpa reported.
The Real Madrid midfielder was spotted a Tottenham's north London training ground shortly before the 1800 BST cut-off after a late swoop.
"It's still dragging on. We are just waiting to see whether it's all gone through," manager Harry Redknapp told Sky Sports.
"We are waiting for clearance. The chairman is dealing with it and Darren Eales the secretary, there is nothing more I can do now."
The decision to go for Van der Vaart took the football world by surprise, and Redknapp admits he only turned his attention to the Netherlands midfielder when it became apparent his price had dropped significantly.
"I think he was going to Bayern Munich yesterday for about 18 million pounds (27.6 million dollars), but suddenly it became an awful lot cheaper," he went on.
"He is available now for about 8 million pounds. He is a quality player. He is a Dutch international and a great footballer.
"For that sort of money, he is a top player and he will improve us for sure. We have made the effort, whether we can pull it off or not we will have to see.
"I am hopeful. It could happen. It was a last-minute job. When I came in this morning it certainly wasn't something I was looking to do."
Redknapp also confirmed that he had made a late attempt to sign Ryan Babel from Liverpool.
Babel was also linked with a move to West Ham United, who would apparently have offered Carlton Cole in part exchange, but he remains at Anfield.
