Arsenal transfer officially confirmed as statement reveals £60m release clause

Porto have confirmed that they've signed Arsenal defender Jakub Kiwior on a permanent basis for £14.6million. Kiwior, 26, joined the Portuguese giants on loan in September but has now put pen to a paper on a four-year contract. The Poland international's move has been announced after Porto won the Primeira Liga title for the first time since 2022 with two games to spare. Alongside compatriot Jan Bednarek and former Chelsea star Thiago Silva , Kiwior has formed part of a formidable defensive unit which has conceded just 15 goals. Under Francesco Farioli, Porto have lost just one league game. The newly-crowned champions will pay a fixed fee of €17m (£14.6m) for Kiwior plus €5m (£4.3m) in potential add-ons. Arsenal, who stumped up £21m to sign Kiwior from Italian side Spezia in January 2023, will also receive €2m (£1.7m) on any future sale. The defender will also have a €70m (£60m) release clause in his contract WORLD CUP LEGENDS: The stars who lit up football's greatest tournament - Buy the Special Edition today In two-and-a-half years at Arsenal, Kiwior made 68 appearances, largely as third-choice behind star defenders William Saliba and Gabriel Magalhaes . The highlight of his Gunners career was two excellent performances against Real Madrid in last season's Champions League quarter-finals. Kiwior had multiple chances to leave Arsenal prior to last summer, but it was reported that Mikel Arteta blocked his exit. In pre-season, the 26-year-old went to Arteta and directly asked for a transfer. Speaking to Polish outlet Laczy Nas Pilka , Kiwior explained: "The last [conversation with Arteta], no [it wasn't difficult]. We already knew then that I would go on loan to Porto. The coach emphasised how big the club was and wished me luck. Who should Arsenal sign this summer? Let us know your picks in the comments section . "The earlier conversation, when I asked for the loan, was more difficult. I'd never done this before [asked to leave], but I felt the time had come to speak with him face-to-face. He understood me and supported me." Like at Arsenal, Kiwior has been used as both a centre-back and on the left-hand side of a back four. He's made 33 starts and four substitute appearances. Porto were beaten by Nottingham Forest in the quarter-finals of the Europa League last month and they're also out of the Taca de Portugal. But thanks to their title win, they'll be back in the Champions League next season. Join our new WhatsApp community and receive your daily dose of Mirror Football content.
