Well this time I'm not worried about the actual personnel. My concerns are simply because of our endless defensive failings under Arsene Wenger and because we have one the most unrelenting injury records in the history of this sport .
In every defensive position from GK to DM we have a good player and also at least one player behind them that can do a solid job.
Cech and Ospina,
Bellerin and Debuchy,
Mustafi and Mertesacker,
Koscielny and Gabriel,
Monreal and Gibbs,
Xhaka and Coquelin,
And we still have the likes of Holding and Elneny to support those positions if needed.
It's certainly a visible upgrade to last season. We have quality in depth now. Injuries would still sting and they will happen, but for me, injuries in defence are likely to be less damaging this season.
