Guardiola's side may have won the Premier League at a canter this season but the Catalan coach is still keen to strengthen when the transfer window reopens.
The City boss is understood to be keen to sign a midfielder and a forward, but Guardiola is also expecting a few players to depart.
"The main target was to win the title," said Guardiola, as reported by the Manchester Evening News. "After that we are going to talk to the club about the players, about the squad for next season. What we need, which players decide to stay, which players want to leave.
"Maybe some play not so much and want to leave."
