"Martin played at left back on Tuesday night, having played in midfield, right back and centre back, and I thought he was outstanding," enthused Boothroyd to the CT.
"He is one of those players that because he is so good he can play anywhere and that becomes a problem for him because you have your starters in your mind, but I thought he was excellent at Shrewsbury, defensively sound and didn't have a problem."
" He takes things out of the air, he keeps the ball and can use his left foot, so wherever you play him he doesn't have a problem and he is a really good player to have. He really impressed me the other night and he has pushed himself for a starting slot against Portsmouth which is the main game for us."
Boothroyd then turned his attention to Cameron, saying: "Nathan at centre back is an 18 year old who I think is going to be a superb player and he has come into the team. What people will find about me as we go along if that I am really not too bothered whether a player is experienced, quick or technically good." 
"It is whatever fits the balance of the team and those two, over the last two or three games have not necessarily given me a problem, but excited me and they could start against Portsmouth."
