REAL MADRID are constantly keeping tabs on Liverpool star Sadio Mane, according to reports. Mane, 25, has proved to be a vital cog in Jurgen Klopp’s Liverpool side since signing from Southampton for £34million in 2016. He has hit the ground running this term too, scoring three goals in his opening four Premier League games. The Senegal international is currently serving a three-match ban after seeing red for his horror challenge on Manchester City keeper Ederson in their 5-0 defeat at the Etihad. Mane looks set to return in the Champions League to face Saprtak Moscow next Tuesday (7:45pm).
