Ipswich kept alive their faint hopes of securing a Sky Bet Championship play-off place as they piled further misery on relegation-threatened Sunderland at the Stadium of Light.
Joe Garner's first-half strike preceded an own goal from Adam Matthews on the stroke of half-time, with Ipswich's 2-0 win ensuring Mick McCarthy made an enjoyable return to Wearside.
However, for Sunderland boss Chris Coleman, there was yet more disappointment as his side remained rooted in the Championship's bottom three, just one point off the foot of the table.
Coleman named all three of his deadline-day signings in Sunderland's starting line-up, but any hopes of a radical change of fortunes were dispelled in the opening 45 minutes.
