I fancy us to beat Riga. Qarabag or Partizani will be a massive test, but we have the safety net of the Europa League if we don't get through that.
Another tie that caught my eye was Crusaders (potentially) facing Wolves. The one thing going in Crusaders' favour is Wolves' struggle at beating weaker teams. They may have beaten each of the Premier League's top 6 except City last season, but they also lost home and away to Huddersfield.
