Derby County failed to reach the play-offs and supporters weren't happy.
Many, though, seem to be losing faith in the former England boss. Derby's 3-0 loss to Reading saw the Rams produce a limp performance when they needed a strong one most. And McClaren's men missed out on a place in the play-offs as a result.
It wasn't just a result of that game, however, it was the result of months of Derby struggles. It's no coincidence, meanwhile, that it has coincided with heavy speculation that McClaren will take over at Newcastle United next season.
Fresh reports as recently as today from the Chronicle suggest the Rams boss will hold talks with Derby about his future amid Newcastle interest.
But so frustrated are some Derby fans with McClaren that they have reacted to their play-off failure on Twitter by essentially telling Newcastle he's all theirs if they want him. Injuries have certainly cost County in recent months but many supporters feel there is more to it. A lack of bottle, tactical mistakes - take your pick.
With Newcastle and Derby both losing 3-0 on the same day, is McClaren the perfect match for the Magpies? Or should Derby fight to keep him as he is a man with a long-term plan...?
#dcfc McClaren has done a poor job simple Taken the club backwards in regards of team spirit and work ethic. Too many mercenaries. Sack him— Finman (@Finman617) May 2, 2015
If McClaren is going, get him gone ASAP. What a time to not show any fight. Awful. #dcfc— Theo Cummins (@theocummins) May 2, 2015
It's not the form, it's not the bad defending, it's the barefaced lies and lack of loyalty that have destroyed my faith in McClaren. #dcfc— The Ram Wagon (@Ram_Wagon) May 2, 2015
We started going downhill when all these Mclaren Newcastle rumours started. If he wants to go. Let him. I'd be more than happy. #dcfc— Declan New (@DeclanNew) May 2, 2015
