Lawrence Dallaglio knows a thing or two about success.
The three-time Lion collected four Six Nations titles and the 2003 Web Ellis Trophy on England duty and won 11 domestic trophies during his 18-year career in the game.
That included six Premiership titles for London Wasps, and now in his role as presenter/commentator for BT Sports he is keeping a keen eye on the current crop of players vying for the Aviva Premiership title.
And with just four rounds left of the regular season, the former England captain believes it is up for grabs:
"I don't think Saracens are unbeatable. They are obviously a very strong team and they have all but sealed not only a home semi-final but in all probability top spot," he told GiveMeSport during an exclusive interview.
"They are still alive in Europe as well but they're not the defending champions and we're now down to the business end of the season."
Saracens have amassed 72 points and are certain of a playoff berth as they sit atop the table, but there is a fight on below them to fill the final three spots that will ultimately contain this year's Premiership winner:
"I think there is still all to play for in the top four. Saracens will be there, Northampton probably will be there, Leicester, Bath, Harlequins and Sale are all competing for those final two places," Dallaglio continued.
Sale (51 points) and Harlequins (49 points) face the toughest challenge to make the top four, but with mouth-watering fixtures such as Quins vs. Leicester (April 18th), Sale vs. Leicester (May 3rd) and a potentially crucial Harlequins vs. Bath fixture in Round 22 it promises to be a tight next few weeks with plenty of points, and bonus points, on offer:
"Anything can happen. It's very exciting and Sale have thrown their hat into the ring so they look like they are challenging as well.
"It promises to be a race right to the end and a very tight finish," he told GiveMeSport.
Speaking ahead of Bt Sport's live rugby show, Rugby Tonight, Dallaglio also refused to write off Worcester despite the Warriors seemingly adrift at the bottom of the table with just one win in the league to date:
"They've given themselves a slim chance (with last weekend's 17-12 win against Newcastle).
"I think it's going to be tough for them but I think rugby is often about living in the moment and when you've lost 22 games on the bounce just winning a game, and having a six hour bus journey back from Newcastle was a huge victory.
"I am sure that their confidence and their mood might change dramatically in the next couple of weeks."
Dean Ryan will certainly have his work cut out if his Worcester side are to pull of a miraculous recovery but, much like Lawrence Dallaglio during his playing days, they will certainly not give up until their fate is mathematically confirmed.
