Liverpool midfielder Adam Lallana admits the manner of his departure from Southampton was difficult to take.
The former Saints captain, 26, has denied reports he issued Southampton an ultimatum, but is realistic about how fans will respond to him.
"I'm not stupid enough to think the way I left didn't leave a sour taste in a few people's mouths," said Lallana.
The England international continued to BBC Radio Solent: "I regret the way I left. I regret bits and pieces of how it happened and it got nasty. It was sad the way it happened.
"What is true is that when I knew of Liverpool's interest and that they had put a bid in, I did say to the club it would be my wish if they could negotiate a fee for me to move on.
"Not for one second did I say I wouldn't play for the club again. I'm man enough to say it was my choice and my decision for me to move on."
