Toure scored twice while substitute Wilfried Bony reminded Swansea of what they were missing as City made sure they will be among the trio of English clubs guaranteed entry into the Champions League group stage, with the fourth-placed club having to enter a qualifying round instead.
Goals from City captain Toure and James Milner had put the visitors in control only for the home side to draw level through Gylfi Sigurdsson and Bafetimbi Gomis.
Toure’s future at City – fuelled by some provocative comments from his agent – has been the subject of intense speculation, with many observers feeling he hasn’t hit the same heights as he did when the club won the English title last season.
But Pellegrini said he had never lost faith in the ability of the 32-year-old Ivory Coast midfielder.
“I didn’t have any doubt about Yaya,” Pellegrini??told Sky Sports. “Maybe the media started with him after his birthday. After that he went to the Africa Cup (of Nations) and we couldn’t win (the Premier League).
“Maybe an important player has more criticism, but I never had doubts what he is like as a player and his commitment to the team.”
Pellegrini added: “We needed to win to ensure we were in Europe.
“It was an open game. We conceded two easy goals but I am happy with the performance against a good team.
“We know we are in a very difficult league. We have four or five very strong teams with the same money to spend so it’s not easy to be champions every year.
“If you cannot be champion, it’s important to finish in the position we are. This year I think we lost too many point against teams in the relegation positions and also in both cups.
“We need to improve a lot of thin but I am absolutely sure that we will be a very strong team next season and we will be involved with the title again.”
