Dennis Greene believes Kaine Felix will have to change his mindset to be more effective in attack.
Boston United were knocked out of the FA Trophy last night, as goals from Jason St Just and Ryan Kendall saw North Ferriby leave the Jakemans Stadium with a 2-0 replay victory.
But with the Pilgrims trailing 1-0, Greene was adamant winger Felix should have been awarded a spot kick after being clipped in the box by defender Nathan Peat.
But the teenager opted to stay on his feet and chase the ball rather than throw himself to the ground, an honesty the United manager feels penalised his own side.
“At the end we should have had a penalty for Kaine,” Greene said. “Kaine’s been penalised for not diving.
“He stayed on his feet because he’s 19 and he’s honest. When he gets to 24 and he’s learned a little bit more he could go down.
“He got contact, the fellow’s nudged him, and if he goes down he’s got a penalty.
“On the box the other day, Gary Neville says people are getting penalised for staying on their feet and you can’t blame them for going down.
“The referee should still give the penalty because he was caught, even if he did stay on his feet.”
