Atletico Madrid head coach Diego Simeone says the side are different to the one when Antoine Griezmann previously left and has called for patience with the French forward.
Griezmann was replaced in the 67th minute with Atletico trailing 1-0 against Getafe on Tuesday, before Luis Suarez netted twice to complete a fine comeback.
The France international was making his fourth appearance for Atletico since returning from Barcelona on deadline day, having left for the Blaugrana in 2019. Griezmann is yet to score for Atleti in his second stint at the club.
"It is normal. He was very enthusiastic to return," Simeone told reporters after the game.
"He is in the process of adapting to this Atletico, which is not the same as the one he left but I have no doubts that it will be what we expect. We are fortunate to have him.
"Atletico generated other things last season… now we understand that with the players we have these systems can also enter.
"The team has more associative play. We are on a path for everyone to adapt, not only Griezmann, but also Rodrigo [De Paul]. Today he did very well. He came on to give us more stability."
Atletico's comeback was aided by Carles Alena's 74th-minute sending off, dismissed for a second yellow card upon consultation with the VAR.
Suarez equalised in the 78th minute from Hermoso's ball into the box, before the Uruguayan headed a 90th-minute winner from Sime Vrsaljko's hopeful cross.
The brace ended Suarez's slow start to the campaign, having only netted once in Atletico's five games prior to the Getafe clash.
"Anyone would have removed Suarez and Suarez scored goals," Simeone said.
“We chatted at half-time and then, even aside from the goals, we saw another team that played with more offensive forcefulness. We have to continue managing that and wait for our most important players to hit their best form."
The result lifts Atletico above Real Madrid into top spot with 14 points from six games, although Los Blancos have a game in hand against Real Mallorca on Wednesday. Simeone conceded his side are yet to find their best form.
"We're at the start of the season," Simeone said. "There are many situations that the team needs to overcome, the team hasn't been as we would like them to be. The game was against a difficult opponent, who aren't going to lose all season and are dangerous."
