Chelsea's heach coach, Maurizio Sarri, has praised Athletic Bilbao's Kepa Arrizabalaga as the club closes in on a deal for the Spain goalkeeper for a world record £71.6m.  With the Blues' current keeper Thibaut Courtois absent from training on Monday and Tuesday in an apparent attempt to force a move to Real Madrid, Chelsea have identified the 23-year-old as a potential replacement. 'I saw [Kepa] one year ago, my first impression was that he is a very good goalkeeper, very young but very good,' Sarri said on Tuesday after Chelsea beat Lyon on penalties after a goalless pre-season friendly at Stamford Bridge. Sarri also hinted that Eden Hazard is likely to stay at the London club.
