Arsenal: 4 David Luiz alternatives for Villarreal

2. Chambers at Centre-Back and Hector Bellerin at Right-Back

When Luiz was withdrawn the decision was to bring on Chambers instead of Holding. Still operating with the back three, Chambers came in to centre-half with Bellerin remaining on the field to maintain pace in wide areas.

Considering how hideously immobile the back four was in Spain, adding some legs at full-back has to be in Arteta’s mind to provide something in the way of balance. If he sticks to this system, Bellerin will have more freedom to push up and then Chambers can even slot into midfield to form a double pivot with Thomas Partey.

Arsenal have to score and if Villarreal do they’re looking at two minimum for extra-time, thus a front foot approach may either be the starting mantra or what the side build up to as the match goes on.

Chambers has better long-range distribution than Holding and is more adept at carrying the ball out from the back, while he can cover his full-back to a decent enough standard, albeit not as well as Holding. Some of those qualities may need to be sacrificed in favour of what can be brought to the table in an attacking sense.

Of course, when was the last time Bellerin played right-back with Chambers at centre-back and Mari/Gabriel alongside him? The answer is never. Arteta will be woe to change his defence up too greatly (you’d think, anyway) given the scale of the fixture, even if in terms of suitability it may be the best group to go with.
