Bacary Sagna says Arsenal need to strengthen the spine of the team.
The former Gunners defender feels the club should invest in more depth down the middle of the park, particularly in defence where they were fortunate to see their starters go relatively unscathed last season.
Speaking to Paddy Power, Sagna explained why he feels it's important for Arsenal to focus on shoring up that part of the squad.
“Arsenal should sign another centre-back," Sagna said. "William Saliba and Gabriel stayed injury-free this season, but they had many games and would want to rest them at some point.
"You need to cover the positions as a team – they should sign one centre-back, one holding midfielder and one striker.
“The centre-back position needs to have some depth. At some point, they will suffer from tiredness, and Arsenal need to be able to bring someone on without changing the shape of the team.
"They need someone solid that can take responsibility, has experience of this pressure and can keep up with the high level of the team.”
