Went to check on transfermarkt if i could find games of him playing as a left sided centerback in a three and found he actually played as a leftback as well
They only have one game listed but out of 413 games they only have 80 games with marked position so most likely he has more. https://www.transfermarkt.com/spielbericht/index/spielbericht/1054754
That would have been useful. For all I know you could have been playing Antonio Valencia at leftback and clearly that isn't a great idea.
Anyhow, missed the deadline, not that it made any difference. That front 6 was really tasty and loved the Viduka pick. He would have been in his element, massive kudos for that.
Defence was very messy though and unnecessarily so.
