Unai Emery will look to strengthen his Arsenal defence considerably this summer and is set to offload Laurent Koscielny and Nacho Monreal as part of a major rebuild.
Eight teams conceded fewer goals than Arsenal in the Premier League last season, with their defensive record closer to 17th-placed Brighton than any of their top-four rivals.
Emery changed to a back three to try and shore up the defence and stop his side leaking so many goals, but The Sun report that he wants to revert to a back four next season.
The Spanish coach was not pleased with the side’s displays when using a three-man defence, with the tweak failing to make Arsenal any more solid but hampering their overall play.
While the Gunners’ attack was particularly ferocious thanks to a strike partnership of Alexandre Lacazette and Pierre-Emerick Aubameyang, the defence conceded 70 goals in all competitions.
Emery has already let Stephan Lichtsteiner leave the club, electing not to trigger the extra year clause in his contract, and others are expected to follow.
Captain Koscielny only has one more year left to run on his contract and will be allowed to leave if Arsenal receive a suitable offer, while Emery is also prepared to cash in on Monreal.
The club have been looking at fresh left-back options to compete with Sead Kolasinac and also want cover for Hector Bellerin at right-back, with PSG’s Thomas Meunier linked.
Unfortunately, Emery’s overhaul must be done on a shoestring budget after the side failed to qualify for the Champions League, meaning they could be priced out of a move for Sampdoria’s in-demand centre-back Joachim Andersen, who is valued at £25m.
