#1 Antoine Griezmann (Atletico Madrid to Barcelona)

After three and a half years with Atletico Madrid, French star Antoine Griezmann has decided to leave the club if the reports are to be believed. Rumours about the 26-year-old joining a new club have been around for sometime, with the player being heavily linked with Manchester United in summer.
Even though Barcelona is placed first on the La Liga points table with a five-point lead over second placed Valencia and they are expected to bring in Philippe Coutinho, the addition of Griezmann to the squad could make them the force they used to be.
The former Real Sociedad player could make the Catalan club genuine contenders for this season's UEFA Champions League.
Barcelona's current number nine Luis Suarez has not been able to hit full form. The 30-year-old could be past his best days and the Spanish club might need to look for a replacement. Griezmann is that right striker who can link up with Lionel Messi and take the club to higher levels.
There might not be any much truth in this transfer rumour, however Griezmann happens to move to Barcelona it could be one of the biggest transfers to take place in January if not the biggest.
