Manchester United hero Sammy McIlroy is unhappy with the attitude of fans this season.

Summer signing Fred has struggled to fire this season while Alexis Sanchez, who joined in January, continues to misfire.

And McIlroy has appeared to suggest the reason why players haven't settled in is because of the crowd's demands over the playing style.

"Manchester United have spent a lot of money. You go around and buy players and some who have come to Manchester United don't hit it off right away because of the crowd and how they want [them] to play," he told Love Sport Radio.

"The pressure is on these players that come to the club. They find it sometimes takes a long time to get into their stride."
