Jason Robinson is delighted his former club Sale have drastically improved after battling relegation last season.
Sharks have won their last four Premiership games and are just one place outside the play-offs.
The World Cup winner has applauded their transformation under Neil Diamond.
"It's been fantastic the way Sale have played this season. Mike Forshaw has done some really good work in Sale's defence and they're not the pushover side they used to be," Robinson said.
Danny Cipriani was named March player of the month and his performances at fly-half could help the Salford club make the Premiership semi-finals next month.
They need to carry their recent form into tonight's home game against Harlequins, who are just two points behind Sale in sixth.
With England duo Mike Brown and Danny Care in Quins' backline, Robinson acknowledges Sale will have to combat a dangerous side to win their fifth straight match.
"If you let them get quick ball they'll punish you so I'm sure the defence will be tested, but it's going to be a cracking game," he warned.
Despite Harlequins possessing other England internationals such as national captain Chris Robshaw and prop Joe Marler, Sale's title-winning skipper feels the Sharks have a decent chance of victory.
"They've got their work cut out against what is a very, very strong side but they've been playing with confidence and getting results," Robinson added.
