Oliver McBurnie bags debut double as Swansea ease past Peterborough
Former winners Swansea made a grand EFL Cup entrance as they breezed to a 3-1 success at Peterborough.
A slick Swans side, featuring four men who starred at Wembley when they lifted the trophy in 2013, sailed through a second-round test courtesy of a first-half super show.
Two fringe players came to the fore as boss Francesco Guidolin rang the changes.
Rookie striker Oliver McBurnie enjoyed a dream debut when hitting a deadly double-blow just before the break after having a prominent role in an early opener from Jay Fulton - also his first senior goal for the club.
Speedster Jefferson Montero carved out the breakthrough after 15 minutes. His cross from the left picked out McBurnie, who reacted quickly to nod the ball into the path of Fulton to head home, after seeing his initial effort saved.
Nathan Dyer squandered glorious one-on-one opportunities to increase the advantage either side of the half-hour. His first effort was kept out by late Posh goalkeeping call-up Mark Tyler, who was promoted from the bench after Ben Alnwick picked up an injury in the warm-up, before he dragged another golden chance wide.
Tyler continued to keep Swansea at bay when finger-tipping a Montero shot onto the far post, but it only provided brief respite as the visitors effectively sealed victory with McBurnie's quick salvo.
The 20-year-old guided a second goal into the far corner from 15 yards on 41 minutes before pouncing again three minutes later to roll the ball into a gaping net after fellow debutant Mike Van Der Hoorn's shot had been saved.
Swansea took their feet off the pedal in the second period, but did still pose an attacking threat with McBurnie being denied a hat-trick by Tyler before Dyer steered another effort just wide.
League One hosts Posh were much improved after the break and Swansea goalkeeper Kristoffer Nordfeldt had to produce a smart double-save to keep them at bay.
The Sweden international kept out Marcus Maddison's 25-yard drive before also blocking Tom Nichols' follow-up.
But there was nothing Nordfeldt could do to prevent 17-year-old substitute Leo Da Silva Lopes slamming in a terrific, long-range consolation for Posh courtesy of his first senior goal with a quarter-of-an-hour to go.
That denied a Swansea defence featuring Neil Taylor, in his first action since helping Wales reach the semi-finals of Euro 2016, a clean sheet, and they had to survive another scare when Nichols struck a post late on.
But it was still a relatively smooth passage for the Welsh side.
