The goalkeepers obviously trained separately from the rest of the squad and it was very interesting to note just how quick Bernd Leno is around the box.
There may be some question marks over Leno’s ability to deal with crosses that come in, but there is no doubt that Arsenal have signed a keeper who will play the sweeper role very well. It's looked a stand-out quality of his, even during the fleeting time we were able to watch the squad train.
The speed in which he gets out the striker’s feet was eye-catching. If Arsenal are to play a intense pressing game this season, then it will start from Leno.
