The 34-year-old Uruguayan striker left Barcelona last September after Ronald Koeman axed him from his plans at the Camp Nou.
The former Barcelona star scored in Atletico's 2-1 victory over Real Valladolid at the Jose Zorrilla on Saturday to ensure his side lifted the La Liga trophy.
One fan has produced a compilation to highlight Suarez's impact this season as Diego Simeone's men finished two points clear of Real Madrid in the La Liga title race.
The Uruguay international opened up about his troubled exit from Barcelona last summer, saying that he was "underestimated."
Suarez told Movistar: "The situation I experienced last summer was difficult, the way I was underestimated.
"Atletico Madrid opened up their doors to me to keep on showing the player I am."

Simeone led Atletico to their last La Liga title back in 2014, but he insisted that their recent league triumph was "tough physically" in a "really tight season."
The 51-year-old Argentine manager said: "We're knackered. It's been a really tight season with a lot of games.
"It's been tough physically, but in the end, we've got this crucial win and we've managed to win the title.
"The togetherness we have has been crucial to achieving this."
Simeone continued by admitting that the newly-crowned Spanish champions were 'nervous' going into the Valladolid clash.
The Atletico boss added: "We felt the nerves a bit today given it was such a key game, but we just wanted to win so as not to have to think about the result of the other game.
"At the break, we managed to calm ourselves down and we went out there and turned the match around.
"I'd like to thank the fans. They haven't been able to be in the stands but we've felt their support in a really tough year."
