Royals boss Brian McDermott was left to rue a clear injury time penalty denied as his team went down 2-1 away to Stoke City.
It was a first defeat in five for Brian's team, and the home side had a stroke of good fortune when Adam Le Fondre was tripped in the 94th minute but nothing was given.
Brian said, "It's a stonewall penalty. Alfie is gutted, he came straight in and said it was a pen. I've been in to see the referee, unfortunately he hasn't given it. It's last kick of the game, you have to give it.
"It doesn't matter what the ref said to me because I respect a conversation that takes place in private. I knew at the time it was a penalty, it hasn't gone our way but I'm really disappointed because I felt we deserved something. As a manager sometimes you just have to move on when decisions don't go your way.
"It was a tough game, you know coming here it always will be, they've only lost once here this season to Chelsea. We stayed in the game, created chances late on. They had a lot of long balls into our box which you expect, we did OK apart from the set play, then a great bit of skill from them for 2-0.
"We got back into it and at 2-1 I thought we'd get something from the game. I was proud of the character and resilience once again. At half time we changed to 4-4-2, we had a lot of long balls coming down our throat so we tried to get a foothold. Stoke have won the game, Tony will be pleased so good luck to them.
"I'm happy with everything but the result, we will keep going, we move on and look forward to our next cup game."
Meanwhile, Brian confirmed that Danny Guthrie will not travel with the squad for our warm weather training on Sunday as he stays behind with his pregnant wife.
