Chelsea defender Gary Cahill was part of the Bolton side that lost 5-0 to Stoke City in the FA Cup semi-final last season, and is desperate to erase the memory of that crushing defeat ahead of this weekend's Wembley clash against Tottenham.
The 26-year-old England international - who arrived at Stamford Bridge from the Reebok Stadium in the January transfer window - is expected to line up alongside John Terry in the heart of the Blues defence on Sunday, and is keen to forget the heartache that he suffered towards the end of the previous campaign.
"That game is not a fond memory; it's something that hurt at the time and still hurts me now," Cahill told Sky Sports. "But now I have a chance to put that right on Sunday. I have no idea why that result happened.
"People said: 'Did you freeze?' No, we didn't. Everything seemed to be going really well for us as a team in the league, and it was as if everyone had a bad day all at once.
"It was just a freak result. It was a freak game."
The Trotters lost five out of their six remaining Premier League games last season following the defeat at Wembley, and Owen Coyle's side continued to struggle at the start of 2011-12.
As Chelsea prepare for a crucial set of fixtures over the remaining few weeks of the season, with Barcelona in the Champions League semi-final next Wednesday, and key games during the Premier League run-in, Cahill is determined to avoid a repeat of last season's slump, starting with a victory over Spurs.
"It is a defining moment in the season," he continued. "The lads are confident but obviously we realise how big the games on Sunday and Wednesday are.
"When you sign for a big club you are aware that they will challenge for trophies year in, year out and this year they are challenging for trophies again so being a part of a team that wins a trophy would be fantastic.
"It would be amazing for me to win my first trophy but there are hurdles before you can even think of that and we have a massive one on Sunday.
"They (Tottenham) are a hard team to beat. Harry Redknapp is a fantastic manager and he has turned them into a real force this season so it will be a tough game."
