January transfer deals

Samuel Eto'o
"Samuel Stormborn of the House Eto'o, First of His Name, The Unburnt, King of the Forwards, Breaker of Chains, Father of Eagles..." Former Barcelona, Inter Milan and Chelsea forward Samuel Eto'o got a Game of Thrones-style welcome from new club Konyaspor, following the 36-year-old former Cameroon international's switch from fellow Turkish top-flight outfit Antalyaspor.
Marcus McGuane
"Signed for the biggest club in the world and tomorrow I start work." Not a bad January transfer window for 18-year-old midfielder Marcus McGuane, who switched Arsenal for Barcelona and will play in the Spanish giants' B team this season.
Pietro Pellegri
Monaco have cashed in on several of their young stars recently, but the French champions paid £18m to sign 16-year-old Genoa forward Pietro Pellegri in January. He has scored three goals in eight Serie A games.
Tim Cahill
Cahill comes home: Fourteen years after leaving Millwall, Australia legend Tim Cahill has returned to the club where he started his professional career. "The romance of the story is definitely not lost on me," said the 38-year-old.
