Chelsea have turned down Arsenal's offer of £17 million (€20m/$23m) for Defender David Luiz, reports Le10Sport.
The Gunners are targeting defensive reinforcements in the summer, and the 31-year-old Blues defender could fit the bill after he fell out of favour at Stamford Bridge last season.
Arsenal have yet to return with an improved option for the Brazilian. In other news, Borussia Dortmund midfielder Mario Gotze wants to move to England this summer, reports the Mirror.
The 26-year-old is looking to jumpstart his career after he failed to make Germany's World Cup squad this summer.
Arsenal, Everton, West Ham, Leicester and Newcastle are all interested in Gotze, who could cost around £18 million (€21m/$24m).
