3. Kolo and Yaya Toure
Both players played together for Manchester City last season after being reunited when Roberto Mancini signed Yaya from Barcelona. They have both played in Champions League finals and have also performed key roles for the Ivorian national team.
Kolo has moved to Liverpool after receiving limited playing time last year while Yaya's contract was extended at the Etihad Stadium. Both have been very successful and also have another brother, Ibrahim Toure, who plays for Al Nasr in Libya.
