Inter Milan beat Palermo 2-1 at home to restore the Italian champions' six-point lead at the top of Serie A after a troubled week.
Goals by Patrick Vieira and Luis Jimenez settled nerves at the club after coach Roberto Mancini said he was leaving at the end of the season following Tuesday's Champions League last 16 defeat by Liverpool. Mancini changed his mind the following day.
Inter have 67 points from 28 games, while second-placed AS Roma have 61 after coming from behind to beat AC Milan 2-1 on Saturday.
Fiorentina tightened their grip on fourth place, worth a slot in the Champions League qualifiers, with a 3-1 home win over Genoa to move four points ahead of fifth-placed Milan.
Juventus, who are 10 points behind Roma in third, host Napoli later this evening.
