Football isn't just about winning trophies. Of course, it helps, but in the broader sense where football clubs are communities that come together, a certain sense of loyalty and fighting for the cause for years on end are also considered great facets that people tip their hat to.The 2017/18 season saw some glorious eras finally come to an end. The last game - that last farewell - will always be a tear-jerker for fans, players, and managers alike.We look at five great eras that came/will come to an end this month.#1 Andres Iniesta's Barcelona exitAndres Iniesta will leave Barcelona at the end of the seasonBefore Pep Guardiola fine-tuned Andres Iniesta's talent, it was Louis van Gaal who saw potential in the young kid who came through La Masia and gave him a debut."You're going to retire me. This lad is going to retire us all." - Guardiola to XaviHowever, it was Guardiola who unlocked his true potential and Iniesta has since gone on to win 32 trophies with Barcelona. Not to mention, a World Cup and two Euros with Spain.El Caballero Pálido (The Pale Knight) is easily one of the most-loved and respected players in Spain and the world. Not many players get a standing ovation at almost every ground in La Liga - not just because he scored the winning goal in the World Cup final, but also because he chose to share that moment with Dani Jarque - his friend that had passed away prior to the tournament.Iniesta isn't retiring yet, though. He is only leaving Barcelona - possibly for a move to Asia. Being the respectable gentleman that he is, he chose not to play for another club in Europe - lest he faces his former side at some point.After 22 years at #Barcelona, midfielder Andrés Iniesta confirms he will leave the club (and Europe) at the end of the season. Thanks for the memories, Don Andres! pic.twitter.com/jBvOcAAxRc— Sportskeeda Football (@SK_Football) April 27, 2018Spanish football owes him a lot. Once the FIFA World Cup concludes, he will be missed when the 2018/19 season gets underway.
