Having the top two teams competing in the final is all you can ask for and it should be delicious, but it's the top two inches that will decide the outcome.
When you look at the team roster, some of the best players in the world are going head-to-head, but the impact of training in this is huge and the mental aspect will play a big role as well.
Leinster have beaten Toulouse in each of the last four meetings over the past five years, including three semi-final matches, so they have the wood on them in a way they haven't against La Rochelle until this season.
However, Toulouse took it to another level and the final was a different beast. They have won all of the last eight finals they have played since 2006, while Leinster have lost three Champions Cup finals in the past five years.
The final feels very different, and I can say that from experience having been part of a Leicester side that lost three Premier League finals and a European Cup final in the space of four years, as well as winning a few over the years.
I know a fair number of these Leinster players were involved when they beat Racing on the biggest stage of all six years ago, as well as regularly winning the URC title until a few years ago, but there is definitely a mental barrier for them at the moment that they have to overcome. .
They have been the best team in the competition between the pool stage and the final in recent years and have dominated the URC from September to May in the last few seasons as well but have lost in some big knockout matches.
That's not to mention Ireland's recent World Cup quarter-final exit, which many of them were also part of, so they know it's a talking point and they'll be absolutely desperate to get the monkey off their backs.
The Irish county will be hoping that the presence of Jack Nienaber, who doesn't have a bad record in finals, will help and has certainly brought about a change in the way they play.
Of course, they are still more than capable of shining on offense but there has been more focus on executing his blitz defense and they say defense wins championships so we'll see if that's the case.
There is no doubt that Toulouse will break down the backline at times because they are very good at not doing so, so it will be great to see if Nienaber manages to bring the pace up to the scrambling Leinster defense as well.
You generally have to score at least 30 points to beat the French giants, so they will have to find some fluidity in attack and Gary Ringrose is clearly a huge loss in that aspect.
He has not featured for his club since January due to a shoulder injury and they have been doing well without him but he is a bigger threat from outside the middle and I actually think Toulouse might try to expose Robbie Henshaw in defense in number. 13 channels.

Investec Champions Cup
Leinster
Toulouse
Henshaw won the Six Nations with Ireland this year in that position and is used to playing there but I think he is better suited to defending in the central position and Toulouse will send two men into his channel.
Clearly the halves are at the heart of everything these two teams do in attack and ball speed is key for Jamison Gibson-Park, while you need to have at least two men in Antoine Dupont around the fringes of the rocks at all times.
I don't think James Ryan being left out for Jason Jenkins is a big deal, but I feel Ross Moloney was left out of the game on the 23rd altogether after starting the semi-final against Northampton and playing such a big role. this chapter.
Choosing Will Connors over Josh van der Flier is a big decision, even though it happened in the quarter-final against La Rochelle, and is a great indication of how much Leinster has changed under Nienaber.
The world's best player for two years is no lightweight, but Connors is a 6ft 5in player who cuts people down for fun as well as being a threat at the breakdown, and has impressed in both wins over La Rochelle this season.
Van der Flier is one of six strikers on the bench, once again showing Nienaber's influence. This is always a gamble, but it could pay off in the last 20 minutes as happened so often for South Africa.
The main choice for Toulouse by a mile is to opt for Blair Kinghorn over Thomas Ramos at full-back, and again, this points to Ugo Mola's approach as the Scot offers more options in attack, as well as solidity under the high ball.
It is a massive decision to go to a final of this magnitude without Ramos even though he shoots the ball 84% at international level and has never missed more than two shots on target in a test during his career.
It seems even greater when you consider that as many as 19 of the previous 28 Champions Cup finals have been won by seven points and you could shift Kinghorn to the wing but I'm sure Ramos would be in a heartbeat if he played a few kicks that went astray.
I trained Mola in Brave and he hasn't changed his principles since. The best way to beat a blitzing defense is to get the ball out of the tackle and not let it get there, and that's exactly what he wants his players to do.
Whether it's Dupont, Roman Ntamack, Peta Ahke, Paul Kostis or any of the back three, you don't often see them die with the ball in their hands and the strikers are quite adept at clearing the ball.
Mane Mevo is an absolute unit and his fitness will be vitally important but he targets soft shoulders well and gets the ball away and Jack Willis has taken his game to new heights in terms of carrying the ball too.
Toulouse may not have had the best striker on the pitch right off the bat, but Leinster do and it's a really big game for Ross Byrne as he steps out of Johnny Sexton's shadow on club rugby's biggest stage.
He, of course, started last year's final with Sexton injured, and he has started URC finals in the past, but the great man has since retired and this is Bayern's team now, so it's a great day for him to show he can lead them to victory.
I think he's getting some unfair criticism, and let's not forget Leinster have only won the European Cup once in the last 12 years under Sexton, but he knows all eyes will be on him and Toulouse will be targeting him.
The matches are interesting and it looks like the perfect final at the best stadium I have been to in many ways which is Tottenham Hotspur Stadium, so let's hope it lives up to expectations.
Toulouse's impressiveness will have its moments and Leinster may not have the muscle memory to win the last two finals but I think it will be third time lucky for them after losing the last two finals and they will go six points clear.
