Hush my mouth, but...hasn't he lost half a yard of pace since his injury?
He's still outstanding, tricksy, clever, a great crosser of the ball, a brilliant player etc; but I don't remember the last time he knocked the ball past a defender then simply ran round him onto the free ball.
Just me, then?
Yes (as in yes, just you I reckon). A few times since he's come back he's shown incredible speed - in particular I remember a few times where he's anticipated an opposition ball and the receiving player wasn't even in the same postcode when the pass was made, but somehow he's got there first.
As for his game time, it's simply overall load management at this stage of his development (cumulative training and playing). Personally think the club are doing an outstanding job that will benefit him hugely in the long term - same goes for Lallana where we've got far more minutes out of him than anyone expected due to that careful management.
