Speaking to TNT Sports, Toon boss Howe said: "Desperately disappointed. The lads gave so much in that game. We had very minimal recovery time. To produce the physical performance we did speaks volumes for the lads' mentality. Devastated not to win. I think the free-kick changed the game really.
"We had chances in the first half as well. That elusive third goal wasn't there for us today. Overall, there's a very positive feeling of how we played today. Really, really good from the lads today."
On the penalty incident, Howe added: "My opinion, yes. I think it's a clear penalty. Anywhere else on the pitch, that's a free-kick. The player has gone into Anthony aggressively. Too aggressively in my opinion. So I think it was stonewall. The defender was only looking at Anthony and not the ball. I think it's too aggressive."
