Manuel Pellegrini held the first-ever trophy of his reign at the Etihad Stadium aloft at Wembley in the shape of the Capital One Cup and will be keen to add more this season
Two stunning goals in the space of 60 seconds from Yaya Toure and Samir Nasri in the second half overturned a half-time deficit, after the Black Cats had gone ahead early on through Fabio Borini. Jesus Navas came on and added a third late on after Steven Fletcher had spurned a great chance to level at the other end to seal the victory.
The win gave Manuel Pellegrini his first trophy as City coach, having taken over before the start of the season. The Chilean hailed the importance of the triumph after the game, as he looked towards winning more this season.
"I'm very happy," he told Sky Sports. "The team deserve this cup because we played well during the whole cup and scored a lot of goals.
"It's important for all of us - for the players, the club, for me, for the staff - all of us. I'm at a very important club, where you must win trophies."
With the team still in the running for all three other competitions they have entered this season, namely the Premier League, FA Cup and Champions League, although progress in the last one looks unlikely after they lost 2-0 to Barcelona in the first leg.
City trail leaders Chelsea by six points in the league, albeit with two games in hand, while they can avenge last season's FA Cup final loss to Wigan when both meet again in the quarter-finals of this year's competition.
It is highly possible still for City to add those two trophies to their haul, but the majority of Goal Singapore readers doubt their ability to do so. 37.3% have indicated that Pellegrini will win only the Capital One Cup this season, with only 19.6% believing they can win both the league and FA Cup. A further 29.4% feel they should be able to win the FA Cup only, while 13.7% think the league is a more realistic shot than the Cup.
