(CNN) -- Portuguese football coach Jose Mourinho, ever the headline creator, has caused further outcry this week after he substituted Ghanaian midfielder Sulley Muntari from his Inter Milan side during their Italian Serie A clash with Bari. 

Inter midfielder Sulley Muntari was substitued Jose Mourinho for his low-energy levels as a result of fasting. 

Taking a tired player from the field of play was hardly breaking news, at least it wasn't until Mourinho revealed the move had been prompted because the player's perceived "low-energy levels" were as a result of fasting. 

Muntari is a practicing Muslim who, like many of the same faith around the world, is currently not eating during the hours of daylight to mark the Ramadan holy period .Should fasting footballers be dropped by their managers? Sound Off below. 

A discipline that clearly irked Mourinho who said in a post-match press conference: "Muntari had some problems related to Ramadan, perhaps with this heat it's not good for him to be doing this (fasting). Ramadan has not arrived at the ideal moment for a player to play a football match." 

Muslim leaders in Italy have criticized the opinions of the coach known as the "Special One", but Mourinho did not rule out the possibility of dropping the player for the Milan derby between arch rivals Inter Milan and AC Milan this weekend for the same reason.
