Wenger has
mostly used the second string
squad at the start of any season to great effect, most teams aren't at full strength or match
fit and he plays that Wengerball numbers game, throwing in
squad players who are
fit and raring to go whilst the first team get ready, we'll win 2 of our 3 opening games and he'd rather that than splash 100m on 3 players and get the same amount of points.
The problem of consistency and always having a fully
fit side will
mostly boil down to how well AW rotates the
squad, and his use and timing of substitutions...
