The Reds manager spoke after Tuesday's controversial 2-2 draw at the Hawthorns in the Championship.
Nottingham Forest endured a frustrating evening on Tuesday as they were on the verge of victory away at West Bromwich Albion only to be denied by a very controversial goal late on for an eventual 2-2 draw.
Martin O'Neill's charges led early on in the Championship encounter at The Hawthorns as Stefan Johansen scored an own goal after just six minutes, an advantage held come the half-time break.
It didn't take long after the restart for the Baggies to draw level, however, with Jacob Murphy finishing off an attacking move which included Mason Holgate and Jay Rodriguez, but academy graduate Ryan Yates volleyed the visitors back into the lead on 65 minutes.
Then came the controversial moment just minutes from time as Dwight Gayle went down under virtually no contract from Forest defender Alexander Milosevic, and Lee Mason awarded a penalty, which Rodriguez successfully converted.
First up in O'Neill's interview after the game, as published by the official Forest website, was the incident involving Gayle, and he said: "The referee has made an honest mistake and I have spoken to him and that is what he thought he saw. I can't argue with that and I am in no position anymore to argue with it."
The Reds boss then moved on to his side's overall performance, adding: "Overall, I was delighted with the team. Physically they made a big effort, worked exceptionally hard and I was really delighted with them. I'm also disappointed for them and for the fans that we didn't get the three points... I couldn't have got any more from the team."
Here is how some Forest fans reacted to his comments on Twitter:
Bad management to not see out the game won’t make play offs if we keep on dropping points and Watson needs to be dropped puffing every 5 mins ain’t got the legs no more— Zac Demetriou (@ZacDemetriou) February 12, 2019

Love the performance, very unlucky, Can’t help but think though that if we have carried on going forward we could actually would have won, pleased for Yates, but all preformed well, lets just go for it, still time— Steve wheatley (@Tranclet) February 12, 2019
