He had a good patch of form in the second half of the season (finally managed to keep a good level of performances for a longer period of time and also didn't get injured). Taking that into consideration, he definitely could use a slight boost in areas such as ATT, DA, SA or TS. I'll have a look at his stats in the coming days.
By the way, I also read something about his possible transfer to Frankfurt but that was some weeks ago and no news have appeared since then in Czech media. Is there some new info in the German ones?
