I can see the logic in the Welbz starting. If we’ve set up to counter attack/press that suits Welbz well, you can cout on him to put in a proper shift in the final third probably more so than Laca who was pretty quiet last match
In theory Welbeck should be extra focused and motivated to perform after being given an immediate chance to redeem his performance against Stoke.
He’ll know all eyes are on him, He’ll know he’s starting ahead of a £50m signing. This should make him give all he’s got today. If he plays well and scores it’s brilliant management from Wenger but if he doesn’t Wenger is an out of touch dinosaur.
