Salech has been one of Cardiff’s star performers this season, scoring 13 goals in all competitions for the League One leaders.
That is despite him being the target of rough treatment from centre-backs, whose robust challenges throughout the campaign have frequently gone unpunished.
“We do so much analysis on the games. If I’m an opposing manager or an opposing team, I’ll see what you can and can’t get away with against a player with his profile,” Barry-Murphy added.
“It’s been coming for months where he’s been consistently fouled. There’s a lot of talk about what the threshold is this season – the level of contact can be prolonged in more than previous years. It’s got ridiculous.
“He’s clearly been fouled all the time and not got any free-kicks. The interpretation of the new rules is up to the referees, but it’s clear how much you can and can’t get away with and the level of challenges that he’s consistently facing are clearly fouls and not being punished.”
