• Wasps have won only four of the past 15 Premiership meetings between the two sides since Exeter were promoted in 2010.
• In 14 past Premiership finals, the league winners have only gone on to win at Twickenham five times (Sale 2006, Leicester 2009 and 2010, Harlequins 2012, and Saracens 2016).
• All four of Wasps' past Premiership triumphs (2003, 2004, 2005 and 2008) have come after finishing second in the league. This season, they finished first.
• Exeter have not won at Twickenham in six previous visits. But victory for the Chiefs would equal Leicester's Premiership record of 17 matches unbeaten.
• Wasps have won their last 10 finals in all competitions, since Saracens beat them at Twickenham in the 1998 Anglo-Welsh Cup final.

With any major sporting event since the Manchester attack on Monday there has been heightened security in and around the stadiums.

There will also be a minute's silence before the match to remember the 22 victims and those injured at Manchester Arena.

For those interested in these things, JP Doyle will take charge of his second Premiership final this afternoon.

He was also the man selected for the 2014 final when Northampton beat Saracens and today is his 132nd match in charge of a Premiership game.

The last time Wasps, or London Wasps as they were at the time, reached a final, they took home the Premiership trophy when they beat Leicester 26-16 nine years ago.

Eagle-eyed viewers will be able to spot a fresh-faced James Haskell next to Lawrence Dallaglio and Josh Lewsey as the then 23-year-old started at blindside flanker.

Wasps just about hold the upper hand when it comes to meetings this season, having won 25-20 when they met at the Ricoh Arena in September and it finished 35-35 in the reverse fixture in February.

They have also met in the Anglo-Welsh Cup, when they both fielded very different sides to their usual starting XV and the Chiefs won 52-5.

Just had a word with both directors of rugby pitchside here at a sun-drenched Twickenham.

Rob Baxter says the "big question" is whether the Chiefs have learnt from their experiences of last year's final, while Dai Young says Wasps will continue to keep to their attacking style regardless of the pressure of today's occasion.

Why should you be looking forward to this game?

Well, these two are the best attacking sides in the league. They are the top two try scorers. And just look at those conditions, perfect for running rugby.

This should be some game.

From milling about outside Twickenham, it's clear to see the Premiership showpiece is different to most sporting finals.

Yes, there are plenty of Wasps and Exeter shirts, but the number of supporters from other clubs here today is eye-opening. There are Sarries, Leicester, Bath and Northampton fans aplenty, all mixing in.

Maybe they thought it would be their side in action this afternoon, but either way this is certainly a real festival of rugby union.

Breathtaking. Epic. Fiery. Magnificent - take your pick to describe either of the semi-finals.

At Sandy Park, Saracens led until the final moments before Exeter's Sam Simmonds was bundled over to put Chiefs in the final for the second year running.

It also ended Sarries hopes of successive European and domestic doubles.

There was heartbreak for Leicester, but jubilation for Wasps a couple of hundred miles up the road at the Ricoh Arena as Josh Bassett's try two minutes from time won it for Dai Young's men.

Six clubs have got their name on this trophy since the Premiership moved to the play-off format, including Wasps on four occasions.

Will Exeter become the seventh?

A sell-out crowd? Check.

Some of the world's best players? Yep.

Two teams promising to attack? Oh yes.

Welcome to our coverage of the 2016-17 Premiership play-off final.
