Chelsea fans have hailed the performance of goalkeeper Kepa Arrizabalaga following his stunning display against Aston Villa in the Premier League on Sunday, October 16. Graham Potter has clearly decided that the Spaniard is his first-choice goalkeeper ahead of former number one Edouard Mendy. Kepa started the previous three Premier League encounters for the Blues and made a string of wonderful saves at Villa Park.His first major contribution was to stop a fierce Jacob Ramsey strike with a strong right-hand. He then followed that up with one of the saves of the season to deny Villa striker Danny Ings from burying a point-blank header as Chelsea held on to secure a 2-0 victory.Chelsea FC@ChelseaFCMason at the double! 🟣 0-2 [66] #AvlChe144352724Mason at the double! 🔥🟣 0-2 ⚪️ [66] #AvlChe https://t.co/hc6vNYUCkTThe win was the Blues' fifth in succession as they continue to thrive under Potter, with Mason Mount scoring both goals. But Kepa will grab most of the headlines as his Stamford Bridge redemption story continues.The Blues paid a world-record fee for a goalkeeper to sign the Spaniard from Athletic Bilbao in 2018. But his spell in west London started in disastrous circumstances, as a series of errors ravaged the early part of his Chelsea career.Many assumed that due to Mendy's form, Kepa would never get another chance to be the club's number one, but he is grabbing his opportunity with both hands. Following their comfortable win at Villa Park, supporters took to Twitter to heap praise on the much-maligned goalkeeper for another outstanding display:Moinul@Moinul123@ChelseaFC @WhaleFinApp Mount probably MOTM because of the two goals, but Kepa kept us in it in the first half, and i just like a nice redemption story, so I'd say Kepa MOTM. Either player would be very well deserved. Both players carried the team today (RLC, Thiago etc had good games too)461@ChelseaFC @WhaleFinApp Mount probably MOTM because of the two goals, but Kepa kept us in it in the first half, and i just like a nice redemption story, so I'd say Kepa MOTM.
