Calum, looking back on the 2-1 loss at the City ground, says:
"We were in control, 100%, and the lad has hit a decent shot from the edge of the box to get them back into the game.
"Then you are thinking 'is it going to be there day with what has gone on this week?' and that is where you have got to be mentally strong and tighten up the game.
"To be fair, both goals were great strikes, bits of magic - but despite our disappointment we have got to pick ourselves up for Derby now.
"We are all professionals and felt we had done enough to win; we were comfortable, but most goals are scored in the last 15 minutes of games, and that is what happened - it was two wonder goals that won them the game.
"The game has gone, it was Forest's day; we have to forget it now and get back on track - the only way to respond is with a win.
"There isn't much you can say we did poorly on Sunday but we have to move on and there is no point dwelling on it.
"There is a lot of character and experience in the side and we have to use that at Derby."
The West Ham players made their own gesture for Brian Clough on the day, and Calum says:
"We brought a shirt along with us; all the lads signed it and we stuck it on the gate as a mark of respect."
