Harry Redknapp lauded Queens Park Rangers' 1-0 Premier League victory at Chelsea as "one of his greatest wins".
Former Chelsea winger Shaun Wright-Phillips' second-half strike past Ross Turnbull secured QPR's second league triumph of the campaign despite the hosts dominating the encounter.
Still rooted to the bottom of the table, it was the Rs' first win at Stamford Bridge in three decades and Redknapp could not contain his delight at the final score.
“This is one of my greatest-ever victories. It will send shockwaves through the other teams at the bottom," he beamed after the match.
“Even those teams on 20 points would have been sitting at home, seen this result and gone: ‘That ain’t very good for us.’ I know because I have been in that position myself.
“The atmosphere in the dressing room afterwards was fantastic. We’ve got to make the most of it and build on this now.”
Liverpool playmaker Joe Cole has however opted to return to boyhood club West Ham despite Rangers' interest, but Redknapp is determined to strengthen a side which has shipped 36 goals.
"If I can improve the squad in the window it will give us a chance. This win is very important for us when it comes to signing players," Redknapp said.
He added: "They might think that now we do have a chance and it would be nice to try and help us get out of this mess and achieve something. Let's be up for the challenge.
"I lost Joe who would have been my first signing. He probably looked here and thought 'Harry I love you but you're not going to stay up'. I like Joe and he would have been good for me. He's West Ham and they love him there. I thought he was coming for sure but West Ham came in today."
The three points has invigorated QPR's battle against relegation and was the perfect response to their 3-0 surrender to Liverpool at Loftus Road last Sunday. Only goal difference separates them from 19th-placed Reading while they remain five points away from safety.
