2. Play Gibbs and Debuchy as the left and right backs
The one threat that Arsenal need to nullify when they face Liverpool is that of Raheem Sterling who was exceptional against Bournemouth in midweek. Sterling was part of the destructive team that tore apart Arsenal last season and with his pace, he needs to be tracked and defended really well.
Playing Debuchy and Gibbs will give the Gunners that extra bit of pace to deal with not only Sterling but Liverpool’s other wide mean like Markovic and even Coutinho, pace will nullify pace and this would ensure that Arsenal do not get caught out all that often unlike last season.
