Well no one is saying we should be running at high intensity for full 90 mins. It's about management, doesn't mean you have pathetic fitness that you end up last in everything. It's obvious to anyone who watched Manutd how much we lacked in fitness. Liverpool were 5th in distance covered this season, Tottenham 8th, Chelsea 10th, City 12th. Manutd 20th Sprints - Liverpool 1st, City 5th, Spurs 8th. ManUtd 14th. You don't have to outrun everytime, you have to match them for intensity and work rate when needed. Barca was also one of the hardest working team when Pep was the manager, they didn't have "we are Barca, we don't run" attitude.
