3. Antoine Griezmann: Real Sociedad to Atlético Madrid – €30m
Unfortunately for Sociedad, the club are set to lose one of their star men as champions Atletico Madrid look to stay one step ahead of their competitors with a marquee signing of their own.
Griezmann has enjoyed a meteoric rise to prominence over the past two seasons, and in the process became one of the most in demand stars in Europe.
The 23-year-old found scored 16 goals in La Liga last season and his form earned him a call up to the France World Cup squad. Atlético are having to pay the buy-out clause of Griezmann, which is a steep figure at €30m, but the winger has the potential to be worth double that in the future.
