Giaccherini appeared as a 77th-minute substitute for Lee Cattermole in the League Cup Final on 2 March, but was unable to prevent Sunderland losing 3–1 to Manchester City. On 17 April, Giaccherini came on as a substitute with Sunderland trailing 1–0 in the league at the City of Manchester Stadium, and assisted both of Connor Wickham's goals as Sunderland went on to draw 2–2. He scored his fifth goal of the season, and fourth in the league, on 27 April 2014, when he scored the third goal in Sunderland's 4–0 win against Cardiff City, a result which saw Sunderland move out of the relegation zone.
