Kris Boyd believes Derek McInnes may have come to the end of the road at Aberdeen - and reckons Hearts should target him to replace Craig Levein .
The Dons boss has taken them into Europe for the past five seasons, as well as winning the League Cup in the 2013-14 season.
Now though some Aberdeen fans are calling for him to go, and Boyd believes there's a perfect job waiting for him.
The former Rangers and Kilmarnock striker told Sky Sports News : "A lot of the criticism has been unfair but, at the same time, I get the feeling that Aberdeen fans are starting to turn on Derek - which is wrong for me.
"I'd be careful what you wish for because there is no doubt Derek McInnes has done a terrific job there.
"Derek McInnes is not really one for going on about injuries, when teams like Aberdeen, Hibs, Hearts and Motherwell lose players in the transfer window it is very difficult to replace them.
"I've not really seen much about him moaning about losing players. He sees it as a positive in terms of how he has developed the players, given them an opportunity and a platform to go on to a bigger stage.
"They drew at home to Hibernian, finishing the game with nine men, they lost in the Betfred Cup and lost heavily to Rangers but in the previous five before that they were undefeated.
"The recruitment that he has done over the years to build the teams that he has for Aberdeen has been terrific.
"But it is maybe just about time where Derek maybe does look for a fresh challenge because there is only so many years that you can do it.
"I said it a couple of weeks ago - if I was Hearts owner Ann Budge and there was a manager I was looking for then McInnes would be one who I would go and pose the question to.
"If she wanted someone to run the club, run everything, then I think Derek is someone who has done that - he has done it at Aberdeen."
