I'm not sure how many teams have tried to tag Touk before. But usually the first time a player is tagged intensely, the tagger wins the day.
Partially due to the surprise factor, but also because there is a skill involved in working through the tag. Which you only really learn while it is happening to you. You would think that Touk is good enough to work through it long term, but there might be some teething problems due to the lack of help around him in that midfield.
