PFA chief executive Gordon Taylor has branded Luis Suarez's conduct at Old Trafford on Saturday as "disrespectful, inappropriate and embarrassing".
Suarez has found himself in the spotlight again after refusing to shake Patrice Evra's hand before Liverpool's 2-1 defeat to Manchester United.
The Reds striker was making his first start since he completed an eight-match ban for racially abusing Evra in the reverse fixture at Anfield in October.
