Saturday's game is not just about Saturday. The cup final's result will have ramifications for next season, something that was first the case for Wolves with the introduction of the European Cup Winners' Cup (deceased) in 1960-61. It would be preferable if the FA a few years back had tried to persuade UEFA that our cup winners should take up a Champions League place, but a Europa League slot will have to suffice.
You may point out that Liverpool and Chelsea have already qualified for that competition for next season, the Reds through the Carling Cup and the Blues via a minimum sixth-place finish, with the latter hoping to retain their place in the Champions League by winning the final against Bayern in Munich on May 19. But unlike the old days there is qualification and then there is qualifying.
If Liverpool have to rely on their penalties victory against Cardiff then they will be playing in the Europa League's third qualifying round on August 2 and 9 - in the middle of the Olympics - and hoping to make the play-offs on the 23rd and 30th. If the Reds complete a cup double, though, then they will have a bye into the group stages. These calculations are reliant on UEFA sticking by the existing access list, but that is highly likely.
Chelsea could just still finish third or fourth but if they complete a losing cup double and qualify for Europe as the Premier League's sixth team, then it is they who will have to face those aggravatingly timed knock-out games.
If Liverpool win at Wembley and Chelsea win the big one in Munich or achieve a domestic miracle then one team qualifying via the Premier League will be in the play-off, another in the third qualifying round. Otherwise, one of the cup finalists will face a badly disrupted pre-season, with the need to be at competitive level a fortnight earlier than their domestic rivals.
No manager will want to have an early-season embarrassment on their record. The Europa League lacks a degree of glamour but if you have a modern-sized squad then you need competitions in which to rotate and the larger the club, the more you make simply by staging matches.
Winning the cup is all about glory but if you lose the final you would rather forget about it. There is a decent chance that Saturday's runners-up will be reminded about it through every step of a premature pre-season and via matches they would really, really wish to do without.
