Agreed, but have been very impressed by Tuchel; when Mr Wenger retired, Thomas Tuchel was the manager I would have liked to have seen replace him.
Elsewhere, Manchester United and Roma are having a superb game, exciting, thrilling, competitive, and with several goals scored (and posts and uprights also hit), whereas Arsenal could be playing until the end of recorded time - and beyond - before they would find the net, even with the assistance of metal detectors, GPS, and other direction seeking devices.
