PSG reached their second consecutive Champions League final with an incredible 6-5 aggregate win over Bayern Munich.
Ousmane Dembele opened the scoring after just four minutes, and although Harry Kane made it tense with an added time goal, it was too little too late.
The French giants will now face Premier League leaders Arsenal in the final following their win over Atletico Madrid, and Tah believes they deserve to be there.
Speaking to reporters after the game, Tah said: "They deserved to go to the final. Both games were close. They were different games - you can't compare them.
“They won twice so you have to give it to them. They scored the first goal really fast. They defended really good for a lot of minutes. We didn't put enough pressure on the backline.
"It feels very disappointing right now. To be successful you have to deal with difficult moments. You can't always be the winning team. We can be proud of the way we handled ourselves and gave everything.
"It will be a good game (the final) but I'm not focusing on this game."
