Blatter: McGuire criticism
PFA deputy chief executive Mick McGuire believes Fifa president Sepp Blatter should operate in a 'more measured and controlled way'.
McGuire's comments follow Blatter's controversial comments on 'modern slavery' in football.
Speaking of Manchester United winger Cristiano Ronaldo's future, amid interest from Real Madrid, Blatter said that no player should be held against his will.
McGuire feels that the Swiss' 'inappropriate' use of the word slavery rids his argument of all credibility.
"It is so inappropriate that he loses any credibility in his argument," McGuire told Sky Sports News.
"There are some words that should never be used in such a context. The word 'slavery' gets people wound up and destroys any argument that he has.
"I think he does it for effect. By focusing on the Ronaldo's future it creates the greatest interest.
"But I believe he does have a responsibility, considering his position, to look at things in a more measured and controlled way."
