Calderwood is demanding a better performance against Watford

Nottingham Forest manager Colin Calderwood has said the decision to award Swansea a penalty in Saturday's Championship match was unjustified.

Wes Morgan fouled Tom Butler to concede the penalty. Paul Smith saved from Ferrie Bodde who scored on a follow-up.

Calderwood told BBC Radio Nottingham: "It didn't look much if I'm honest and on the video it looked even less.

"It's an unfortunate occasion for us to have a bad decision against us and it puts so much sway on the game."

Calderwood said: "We gave the ball away needlessly on occasions.

"When they had the ball they were excellent, we quelled that in the second half but they were the dominant force in the first half.

"Swansea got well and truly humped last week and they've come back with a real up-tempo performance, so we've got to go to our next home game with the same intent."

The Reds play Watford at home on Saturday.
