The race for Guinness Premiership play-off places reaches a thrilling conclusion on Saturday.

West country giants Gloucester and Bath have already secured semi-final berths on Sunday, May 18 but the remaining two spots are up for grabs.

Here are the permutations for final Super Saturday:

GLOUCESTER: Having led the Premiership for most of this season, Gloucester need one point against Bath to guarantee a home semi-final. Victory means they will finish top, while the lowest position Gloucester can occupy is third.

BATH: A win at Kingsholm would put Bath top of the Premiership pile. A draw or two losing bonus points guarantees second spot, but if Gloucester beat them then Steve Meehan’s men could possibly end up fourth.

WASPS: Lawrence Dallaglio and company head to already-relegated Leeds Carnegie, needing one point to confirm a play-off place. Victory though, especially of the bonus point variety, could see them finish second.

SALE SHARKS: Sale, the 2006 Premiership champions, need to beat Edgeley Park visitors London Irish to secure a play-off spot. Defeat could see them nudged out by Harlequins or Leicester.

HARLEQUINS: Rugby director Dean Richards takes Quins to his former club Leicester, knowing a play-off berth hinges on results elsewhere. Quins must beat the Tigers, preferably with a bonus point, and hope Sale or Wasps are beaten, the latter without a losing bonus at Leeds.

LEICESTER: Leicester can only reach the play-offs if they beat Quins and collect a bonus point, while Sale lose at home to Irish without gaining a point.
