Sunderland midfielder Lee Cattermole has failed to impress the Stadium of Light crowd this term.
Cattermole seems to have fallen completely out of favour with the Stadium of Light faithful, after some poor performances this season.
The 29-year-old has been jeered by Black Cats fans at points over the campaign, with his displays disappointing.
Cattermole was actually sent off in Sunderland’s last away match, against Wolverhampton Wanderers, which will have done little to improve the midfielder’s confidence.
But Coleman insists that Sunderland fans are well within their rights to express their annoyance at Cattermole’s showings.
“He has been here a long time, as have one or two of the other boys,” Coleman said.
“The supporters look at Lee Cattermole and players like that who have been here a while and sometimes they voice their opinions.
“Fans have every right to do that, we only have one set of fans. We can never be critical of the supporters who will be here forever. We won’t be but they will.
“They have every right to say what they want to say, it is their club. His experience of course, in the position we are in, he will be an important player for us.”
Cattermole missed out on featuring in Sunderland’s victory over Fulham at the weekend, as the Black Cats finally ended their long wait for a victory in front of their own fans.
The midfielder will be back and available for selection again at the weekend though, as Sunderland look to move further away from the drop zone.
Sunderland’s next match comes against Birmingham City, and a victory could put four points between them and the bottom three, if other results go in their favour.
