Lucas back fit and healthy gives us a nice selection headache. Allen was poor against United but then again so was the entire team as a unit. I was trying to make a case for one over the other this Saturday, but can't. It's a bit of push for me but if pushed for an answer I'd put Lucas in there. Although they seem to be vying for the one position I view them as a different type of player. They have contrasting styles. Lucas is dependable and takes up great positions to neutralize threats. He is excellent at covering his wings back and keeps us ticking over. Allen is more of a energetic roamer and uses his balance to maneuver and slalom around opponents. Is there room for both? Arsenal will pack the midfield with a million little attacking midfielders.
