Swansea boss Roberto Martinez defended his rotation policy after his side were knocked out of the Carling Cup by Watford.
The Swans had cruised to a 3-1 victory over the same opposition in their Championship clash on Sunday but Martinez opted to rest several key players for Tuesday evening's clash. But Lee Williamson's first-half strike provided sweet revenge at the Liberty Stadium for the Hornets against the home side who made eight changes to their starting line-up.
"I had no regrets about making the changes, but the biggest disappointment was that our performance wasn't up to our normal standard," Martinez said.
"We do not have to be perfect to get a result, and it is a great lesson to be learned by the whole squad.
"Everyone at the club has worked hard to get in this situation and it is frustrating that we have let ourselves down because we gave them two chances and we were unable to control the game."
