Carl Froch was left frustrated by his unanimous points defeat in the Super Six final against Andre Ward last night.
The 34-year-old also confessed that he could not cope with Ward's "defensive skills".
"I had a bad night," Froch told Sky Sports News. "I couldn't get anything going. That's due to Andre Ward's defensive skills. He's very slippery and tricky in close.
"I wanted to put my shots together. He moves low and slips and slides, he's very clever up close. It was very frustrating for me tonight. Fair play to him.
"Up close when he was leaning on me, he seems to be able to get his head there, get his shoulder in the way. He's either up close smothering your work, or he's too far out of range. I could never get my shots away."
Froch is reportedly keen on arranging a rematch.
