Kepa Arrizabalaga has kept seven clean sheets in the Premier League this season and he's determined to do even better by the looks of things.
Arrizabalaga was pictured juggling tennis balls while catching a football at Chelsea's Cobham training ground.
The 24-year-old will be in the starting XI for Chelsea's trip to Wolves on Wednesday night.
Chelsea go into the Premier League encounter on the back of their 2-0 victory over rivals Fulham on Sunday at Stamford Bridge.
Pedro and Ruben Loftus-Cheek were on the scoresheet for the Blues against Claudio Ranieri's side.
They will be aiming to build momentum again after their defeat by Tottenham at Wembley ended their unbeaten run in the top flight.
Meanwhile, Maurizio Sarri says there is no chance Loftus-Cheek will leave Chelsea in January's transfer window.
The England midfielder has been linked with numerous clubs, but scored in Sunday's win over Fulham to show his value to Sarri, who dismissed the idea of a move.
'No. I want him to stay with me, to stay with us. I think there is no chance,' said Sarri, speaking ahead of Wednesday's Premier League clash at Wolves.
Midfielder Mateo Kovacic (ankle) and left-back Marcos Alonso (back) are doubts for the trip to Molineux.
Sarri welcomed Cesar Azpilicueta's new four-year contract and was asked about David Luiz and Cesc Fabregas' futures. The pair's contracts expire at the end of the season.
The Italian said: 'David and Cesc are leaders. And so I think it's very important for me, for the staff, also for their team-mates, if they stay with us.'
Both Luiz and Fabregas are aged over 30 and Chelsea's normal policy is to offer just one-year extensions for such players. That is the sticking point, according to Sarri.
Sarri added: 'The club want a short contract and the players want a long contract. And so it's difficult for this reason. I think at the end we can find a solution.'
