Apologies for a potential shitpost and I know this doesn't matter much but I can't find an accurate answer.

Earlier I posted a comment saying he was 5'10". Which he was according to the usually accurate football manager 16 but then in the new fm16 February update he is now listed as 6'0". However wikipedia and transfermarkt say he's a much bigger 6'3".

EDIT: Here's a somewhat recent article saying he looks unlikely to reach 6'2" for example

EDIT 2: After more research I found he was 6'1" in another fm update
