Daily Mail journalist Paul Brown has said that Chelsea could complete the signing of Sevilla defender Jules Kounde 'quite easily and quite quickly' this summer. The Blues were heavily linked with a move for the Frenchman last summer. However, the deal failed to materialise, as Sevilla were reluctant to accept any offers below the 23-year-old's £68 million release clause.Chelsea could be set to resume their pursuit of Kounde this summer, as they will be keen to sign a replacement for Antonio Rudiger. The Blues have announced that the German will leave the club after his contract expires at the end of the season.Kounde, meanwhile, has been in sensational form for Sevilla since joining them in 2019. He has won the UEFA Europa League and helped his team to third place in La Liga this season. Brown believes Chelsea will acquire Kounde once the UK government lifts the sanctions it has imposed on the club's owner Roman Abramovich, who will then sell the club."It doesn't seem like they have a massive rival to sign him, I think the other teams who are looking for a centre-back are going in different directions. So, that seems to be one they might be able to complete quite easily and quite quickly once the sanctions are lifted, but they are probably going to need somebody else as well," Brown told GiveMeSport.Acclaimed transfer expert Fabrizio Romano has claimed that Blues manager Thomas Tuchel is a massive fan of Kounde. The club have also been provided a major boost in their pursuit of the French defender. The Daily Mail has suggested that the 23-year-old has informed Sevilla of his desire to leave them this summer.Transfer News Live@DeadlineDayLive Chelsea remain confident they will sign Jules Koundé this summer despite the sanctions they are under.The player is interested in a move to Stamford Bridge.(Source: 90min)917101🚨 Chelsea remain confident they will sign Jules Koundé this summer despite the sanctions they are under.The player is interested in a move to Stamford Bridge.(Source: 90min) https://t.co/Ef2ATZl26PChelsea could sign another defender this summerSpVgg Greuther Fürth vs RB Leipzig - BundesligaAndreas Christensen could leave Stamford Bridge this summer, as his contract expires at the end of the season.
