Tiago (Atletico Madrid to Chelsea)
Some sources have claimed that a deal that would see the experienced Portuguese international move to west London has already been agreed.
The 33 year old Atletico Madrid midfielder is out of contract and is set to return to Stamford Bridge after helping his Vicente Calderon side to the La Liga title and a Champions League final this season.
Tiago spent a season at Chelsea before moving to Lyon in 2005, with Micheal Essien moving in the opposite direction, a decision Jose Mourinho has publicly admitted was a mistaken one.
