The squad really needs two more defenders. Either one cd and a wb or two cds.
Personally I'd go with a central defender and wing back. Veltman can do a solid job at wb but I prefer him playing more centrally. Lamptey isn't going to play every game or even a full game every time he plays so it'd be good to have cover for that. March can play there but I want him as the cover for cucurella, who can also act as the squads fifth centre back.
So, as it stands I think the squad is only two players short - the two defenders.
Two out of three from Van Hecke, Clarke and Ostigard then. Job's a good 'un.
