Thanks for the suggestions, guys.
You are definitely right that he needs an update. The thing is - how am I supposed to update anything when there are no official definitions of the "new standards"? I've been following the discussions but there were no clear outcomes or conclusions. So, at the moment I'm very unsure how I would rate any player... and I don't feel confident about making any updates at all.
Still, I'd like to react to some ideas that have been mentioned.
His defence probably is too high, yes. Mainly because of his very attacking style - as for his actual defending ability, it has always been rather impressive (in the Czech league, I mean) and he's definitely not one of those attacking fullbacks who suck at defending. That's why I'd aslo say his Response should be quite a lot above 73, even in the new standards (but as I said, I'm not too familiar with them). I also agree with the Speed suggestions, TS should be above Acc, I'm not really sure if he needs an 85/86 though... And as for his Technique, I'm not sure. His DA is surely completely deserved, it could actually even go up a little bit. Technique is something a bit different of course - but it never struck me as one of Theo's weaknesses...
