His body language last night was a bit of a concern. You can look too much into things, but he reminded me a bit of how he looked in his last season at Barcelona. Sometimes a mans biggest strength can also be his biggest weakness, and Guardiola's intensity, and perfectionist idiosyncrasy has given him great success as a manager, but also as you highlighted, and he's admitted, has given him a short shelf life. After the domestic treble season, giving him a contract extension was an easy decision, but looking back at this season, and what he said in his 4th year at Barcelona, he and the club now have a bit of a dilemma. How long can he go on for? He's been a manager for 12 years now, one being a sabbatical. There's a risk he could become a bit like Mourinho if he stays too long here. Next season is a very important one for him.
