It's not hypocritical on my part at all. You're putting words in my mouth. I never use travel as an excuse for result. It's a part of football. If anything, it's the game the weekend after the CL game that's affected.
United have won every single league game this season after a CL match. Only one of them was a home game (against QPR). The others, away games against Chelsea, Liverpool and City. Yea, I don't have a huge problem with travelling.
You think Barcelona are being picked on? Think about clubs that travel more on average than other clubs in the league. Like Russian teams in the CL. Spartak had to go all the way across Europe for every away match. That's three matches of long travelling whilst only one game for other clubs.
These teams are travelling in the best way known to man, be it by flight, road or train. Jet lag doesn't apply to ground travel and travel fatigue isn't something you should get if you don't have to get up in unusual hours or eat right along the way.
