Dinamo Zagreb in Croatia on Thursday morn. They are unbeaten in their domestic league at home since 2010, so will be a challenge.
Then short turnaround to early kickoff on Saturday against Chelsea. They have a short turnaround as well but they are at home to Maccabi on Thurs so not quite the same...
Then right after that we have Spurs midweek in the League Cup, then Leicester in the league, then Olympiakos mid-week, then ManU at home before the next international break.
Perhaps our most packed group of fixtures for the season. Very tough.
