'Runners-up isn't something we want, ' he said. "It is a tough competition to win or finish second and we are pleased with where we are at the moment". We wanted to finish this campaign like we started it, with a win, and we've done that.
But a combination of Welsh resilience and French profligacy meant the game ultimately went Wales' way, leaving France still without a win in Cardiff since 2010.
Gatland, who coached Ireland between 1998-2001, added: "Congratulations to Ireland on the Grand Slam, it's fantastic and they deserve that, but they'll know they were a little bit lucky as well".
'The way our games went we could've been going for a lot more but this last game we've displayed the character we need going forward.
"We've got to be very positive about this competition, we've got to talk it up say how good it is because I think it's been a very competitive year and there's been some great rugby".
"Today wasn't about the performance it was about the result". The tournament has been very close. "I'd like to think that we have developed more strength in depth than we had at the beginning of the Six Nations".
"But we have scored some good tries and we've created some space".
The visitors started well and Trinh-Duc put them ahead with a fine drop goal. He and Maxime Machenaud missed a penalty each and France lost by a point.
Leading 14-10 at halftime thanks to Liam Williams' opportunistic try and three Leigh Halfpenny penalties, Wales produced a strong defensive effort in the second half to restrict the fast-finishing French to just three more points despite their dominance of possession.
Liam Williams capitalised on Francois Trinh-Duc's mistake to score the first try, but Les Bleus recovered smartly and Gael Fickou surged over to keep his side within touch. They sealed their third ever Grand Slam in this championship by hammering England 24-15 at Twickenham. They played well against Ireland in their first game, the first 40-50 minutes against Scotland, and they were outstanding against England last weekend.
In Rome: Scotland 29 (Fraser Brown, Sean Maitland, Stuart Hogg tries; Greig Laidlaw 3 con, pen) beat Italy 27 (Tommaso Allan 2, Matteo Minozzi tries; Allan 3 conv, 2 pen).
"Sometimes when you are focusing on certain aspects of your performance and trying to improve, then other things you were trying to improve in the past take a second string".
