As has been said many times it all about opinions and FWIW I am a major critic of Dunk but he started off very well and looked assured until he went to sleep to allow the man to get in front of him for the goal after that he wasnt so good and dominating and lost the ball a number of times when...
I would prefer him to play against Leeds than Calderon who is awful at left back as he is always out of position and on his 'wrong' foot, if that is possible for a pro footballer who should be reasonably proficient with both feet. Calderon is an able deputy at every other position in the back four.
