Manchester City boss Pep Guardiola's first season in English football shows how his predecessor Manuel Pellegrini was under-estimated, says former City defender Martin Demichelis.
Guardiola appears set to finish a season without a trophy for the first time in his managerial career.
"You only have to look at City today to see nothing comes very easily even with a fantastic coach," Demichelis said.
"As time goes on everyone will value the work that Manuel Pellegrini did."
Pellegrini won the Premier League and League Cup in his first season at the club after joining from Malaga in June 2013.
