Steed Malbranque, Teemu Tainio and Younes Kaboul have joined Pascal Chimbonda in holding talks with Sunderland.
The Black Cats tabled bids for the Tottenham players earlier in the week and Chimbonda arrived at the Stadium of Light on Saturday morning for talks over a potential transfer.
The French defender's three Spurs team-mates have now all made the same journey to meet with Sunderland boss Roy Keane.
Agent Rudy Raba had stated that Kaboul was not interested in a switch to Sunderland, with Portsmouth leading the chase for the 22-year-old.
However, he has decided to listen to Sunderland's offer before reassessing his options.
Malbranque and Tainio have also discussed personal terms with the club and it would appear they have no future at Tottenham.
