'Surely the ideal solution would be to sign Stones on a free?'

[BBC] [Getty Images] Following the news William Saliba is out for an "extended period" with a back injury , we asked if you think Arsenal need to dip in to the transfer market in his absence. Here are some of your comments: Tom: We have seen in the past that defenders, when give the opportunity, can step up in big moments - like Jakub Kiwior and Cristhian Mosquera. I would give Mosquera a chance to cover Saliba but maybe dip into the market for a replacement for him as there isn't anyone obvious after him. Maybe another young defender or a older experienced player to help in that area! Ken: He missed games last season. No cover is needed as that would be unnecessary stockpiling. Mosquera, Piero Hincapie, Ben White, Riccardo Calafiori and Christian Norgard can all play there next to Gabriel. Paul: Surely the ideal solution would be to sign John Stones on a free? Seasoned Premier League centre-back, bags of experience and can provide cover in midfield too. Great support for younger players as well - instant credibility and respect. MK: We have cover in the centre like Mosquera. Also think that this is a good chance for Marli Salmon to have a shot. Still, I am quite worried because Gabriel and Saliba are the rocks of our defence. Max: Stones is a free agent, starts for England and has experience in winning titles - including the Champions League, no less. Seems perfect as a back-up and is miles better than Mosquera. Chris: We have more than enough talent in the backline to cover with Mosquera, Jurrien Timber, White, Calafiori and Hincapie all more than capable in that centre-back role. I think we should focus more on bringing in a true full-back who can play both sides, such as Djed Spence, Lewis Hall or Livramento (if he's fit).
