Tottenham paid an inflated fee for Scott Parker in order to prevent Jake Livermore from joining West Ham reports skysports.com.
The 21-year-old was expected to head in the opposite direction of the incoming England international, as the Hammers sought cover for the loss of their influential midfielder.
West Ham boss Sam Allardyce has strengthened his Upton Park squad with a number of loan signings, as he bids to bring the club back to the Barclays Premier League.
But Spurs boss Harry Redknapp was determined to keep Livermore at White Hart Lane despite the arrival of England international Parker, and revealed that Tottenham paid more money to get the deal they wanted.
"I like Jake. He's a fantastic boy and he's an established player now," Redknapp told London 24. "West Ham wanted to take him and, in the end, he didn't want to go anyway.
"It didn't happen and I'm pleased to have him here because he's important for us. He'll play in midfield and do a job anywhere for you. I think he has a good future.
"We paid more money for Scott in the end rather than throw Jake in as part of the deal."
With 12 Tottenham appearances already under his belt this season, including games in the UEFA Europa League - Livermore is perhaps gaining better experience than he would have in the second-tier with West Ham - so the decision looks to be a good deal all round.
