The Uruguayan forward - subject of a big-money move from Liverpool to Barcelona in the close-season - has largely struggled to live up to his price tag so far, albeit early in his career at the Catalan giants.
Suarez is no longer the main man in attack and has to share the spotlight with both Lionel Messi and Neymar.
He had scored just one goal in eight Barcelona matches before Wednesday but impressed in a new formation as he netted in Barca's 3-1 UEFA Champions League success against Paris Saint-Germain.
All three of Barca's star forwards scored in a triumph that saw them move top of Group F and win for the eighth game in a row in all competitions.
"We are all happy with him," Ter Stegen said.
"He did a good job today and got his result at the end with a goal.
"He always fights for the team, which is really important. He is really good for the team so I hope he can continue like this."
And despite Real Madrid's superb 19-match winning run in all competitions, Barca, who sit second, are just two points adrift of them.
Given Real's form, that represents a good result for Luis Enrique and a 1-0 win at Valencia last month showed his men had the mettle for a title fight.
French midfielder Abdoul Karim Yoda tops their scoring charts with four but the likes of forwards Babacar Diawara and Alvaro Vazquez need to improve if Cosmin Contra's side are to snare a top-half finish.
History does not make pretty reading for Contra's men, either.
