Arsenal have completed the signing of Brazil defender David Luiz from Chelsea in an £8m deal.
Luiz, 32, joins the Gunners on a two-year contract, with the deal following Arsenal’s £25m deadline day purchase of Celtic left-back Kieran Tierney, 22.
Arsenal manager Unai Emery said Luiz brings “huge experience” and “adds to our defensive strength”.
Luiz takes Emery’s summer spending over £130m after deals for Nicolas Pepe, William Saliba and Gabriel Martinelli.
Having signed for Chelsea from Benfica in a £21m deal in January 2011, Luiz joined Paris St-Germain for £40m in June 2014 before returning to Stamford Bridge in August 2016 for £34m.
He spent six and a half years at Chelsea in all and won the league title, two FA Cups, the Champions League and the Europa League twice.
He signed a two-year deal with Chelsea in May and his departure comes five weeks after Frank Lampard returned to Stamford Bridge to manage his former club.
