As BoA says, the 'lacking energy' was how Calderon described Rovers' performance at Lincoln. That threw me because they'd had two tough games already that week so he should've been expecting a drop off and if he wanted some fresh legs in the team then Reindorf would've seemed an obvious choice. As you say, he's never lacked energy for us, he's been like Tigger on speed whenever I've seen him.
So there's obviously a problem and we can only speculate what that is. The thing I've wondered about him is what went wrong at Norwich. He seemed to be very highly rated there one minute but sent out on loan to the 7th tier and then on his way here the next. Again, we can only speculate about that. Maybe you're right that he acts the big shot at times and that's flared up again now but it's odd because I didn't see any of that in our u-21s, he gave everything and was a team player.
