Yeah, I had similar with my first game at OT v Fenerbahce in the Europa League. It was an 8:05 kick off and I barely made it on time after setting off at 3:30. All the others have been fine though. As long as you set off around 1, you should be golden.
This is my first season as an ST holder too, so you can imagine my surprise when I saw that the first two home games were a Friday and a Monday, considering I only had 7 days of Annual Leave left for the rest of the year, and the midweek games are still to come in the League Cup and the Champions League! I just hope that we get plenty of away draws which are London-based so that I can get to them and still be able to come into work the next day, lol.
