It's best wishes from me and, I'm sure, everyone in Wales to Cardiff City First Minister Rhodri Morgan
Joma has almost sold out of the 5000 limited edition Cup final shirts it had made for the final and expects to sell the last ones before the game kicks off.
National sales manager Mark Godley said: "We're not sold out yet but we're getting fairly close to it.
"If Cardiff win the final then I think we will be back onto the shirt makers at one minute past five o'clock in order to get some more in."
Lord Mayor of Cardiff, Cllr Gill Bird, said: "This is a huge occasion for the city, and if fans weren't lucky enough to get their hands on tickets for Wembley, then surely this is the next best thing.
"I'm sure the atmosphere will be electric with everyone getting behind Cardiff City to lift the cup."
And there have been many good luck messages to the team from the great and the good.
Great Game
First Minister Rhodri Morgan said: "It's best wishes from me and, I'm sure, everyone in Wales to Cardiff City as they prepare to take on Portsmouth in the FA Cup final.
"I'm confident they can really represent the very best in Welsh football and Welsh sport by taking on and beating Portsmouth on Saturday.
"Good luck to the boys."
Even Prime Minister Gordon Brown, a Raith Rovers fan, has wished Cardiff City and Portsmouth, all the best for the final.
Mr Brown said he thought it was going to be a great game and he was looking forward to watching it.
Cardiff City players will parade through the Welsh capital in an open-top bus on Sunday if they win the cup.
Even if they lose, an event will be held for fans to see the team.
