Arsenal suffered a dismal run of form towards the end of the 2018/19 campaign falling out of the top-four in the Premier League and missing next term’s Champions League football.
However, the Unai Emery is keen to bolster his squad starting from defensive options.
Charlie Nicholas has urged the Spaniard to sell three Arsenal players before bolstering his defensive options.
He told Sky Sports: "We’re being slow again in the market. The manager has identified plenty of options. Defensively is the key area. I just hope we don’t delay these deals. Arsenal need to get into the market. We can’t afford someone like Aaron Wan-Bissaka but we need a whole new defence really. We need three defenders to come in which will cost £60-£70m.
"Who can they get out of the door? If you can get the right offer for Mesut Ozil you’d sell. Mkhitaryan can go and you want to keep Pierre-Emerick Aubameyang and Alexandre Lacazette. Torreira seems to be interested in going back to Italy. If you can get the right money: take it."
Arsenal have been linked with moves for Ryan Fraser, Alexis Claude-Maurice, Gabriel Martinelli, Yannick Carrasco and David Neres this summer.
