Manchester City captain Vincent Kompany says it was important they spent during the summer market.
Manuel Pellegrini spent big again during the transfer window, snapping up Eliaquim Mangala for £32million and his former Porto team-mate Fernando for £12million.
Kompany told France Football: "To me the most important thing was not that I signed, but that I saw David Silva, Samir Nasri, Aleksandar Kolarov and Yaya Toure doing the same.
"That was a strong signal. All of those players could play for the top teams in the world, but they have decided to show faith in City and the project at the club.
"Personally, I have a very strong relationship with the club, so the decision to extend my stay was easy. I am looking to the future."
Kompany added: "The summer reinforcements? People should see that as logical for a team like us, to get reinforcements every year.
"We are forced to. That is a fact. Joleon Lescott is leaving? We must get reinforcements for that position. Javi Garcia is leaving us? We have to add a player in that position."
