After two average seasons for Panathinaikos he excelled in the 2011/12 season and scored no less than 15 goals in 17 league matches. At the height of his powers he injured his knee in January and missed the rest of the season when Panathiniakos finished runners-up to Olympiacos. He terminated his contract with Panathinaikos in January 2013 after he had still not recovered from his injury. A statement released by Panathinaikos said: “Seba’s talent, his contribution to the team, his passion and the bond he formed with the fans has earned him a special place in the history and the heart of the club.”
After recovering from injury Leto joined Serie A side Catania, playing in 26 Serie A matches in 2013/14 scoring three times (against Torino, Atalanta and Sampsoria). The Sicilian club was relegated after finishing 3rd from bottom with only 32 points from 38 matches and with the club struggling financially the following season he was loaned to Argentine side Lanus in January 2015. After a year in his homeland he returned to Siciliy, by which time Catania were in the third tier and he was given a free transfer, rejoining Panathinaikos where he scored a respectable five goals from twelve appearances in the rest of the 2015-16 season. He again had a productive season with Panathinaikos in 2016-17 scoring eleven times but two thirds of his appearances were as a substitute.
Leto spent the first half of 2017-18 with Emirates FC in the UAE Gulf League, playing nine times before leaving. He had talks with Fulham in January 2018 but no deal was struck . In June 2019 Leto announced formally that he was ending his playgin days and taking up a coaching role in Iran with Esteghan FC.
