Arsenal have to offload many stalwarts at defense.

Arsenal have been facing defensive issues for past couple of years. In the pursuit of a lucrative solution they signed the likes of Luiz, Sokratis, Mustafi and some others but could not get desirable results. Now it has become a big issue for Arteta to offload the stalwarts to make room for new signings and youngsters. Last year singing and on loan defender Saliba will join the row when the season completes. And injured defender who had showed full potential and commitment before injury, Calum Chambers and on loan young defender Rob Holding will contend for the place at the heart of defense. Another defender, Pablo Mari is expected to turn the loan status into a permanent one.
So, there will be 6 players for just two positions. In this situation Arteta has to offload a couple of defenders to make a balance in resource allocation and time allocation. It is difficult to find some suitable buyers for Mustafi and Sokratis. This situation may halt the process of defensive overhaul for Arteta who intend to add some quality with new signings in the defense.
