Capital One Cup: Newcastle slump as heat turns up on manager Steve McClaren
Lewis McGugan piled further misery on Steve McClaren as Sky Bet Championship side Sheffield Wednesday dumped Barclays Premier League Newcastle out of the Capital One Cup.
A Wednesday side featuring 10 changes to the one which started Saturday's 3-2 victory over Fulham secured a famous 1-0 victory at St James' Park with the Magpies, who have publicly reversed their recent policy of dismissing the domestic cup competitions as an irrelevance, turning in another dreadful display.
McClaren's men did not manage a single shot of note on target over 90 soul-sapping minutes and have now won just one of their eight games this season.
The former England manager fielded as strong a team as he dared, but having insisted in recent weeks that he has enough strikers with the club having not pushed home their interest in QPR's Charlie Austin during the summer, started without any of them.
His hands were tied to a degree with Aleksandar Mitrovic completing his three-match ban and Papiss Cisse and Emmanuel Riviere injured, but with Ayoze Perez sitting on the bench, it was number 10 Siem de Jong who was asked to lead the line.
Not unexpectedly, it was a task which proved beyond the Holland international as ponderous build-up and woeful service shackled the Magpies during the opening 45 minutes.
Moussa Sissoko, one of the few men to inject any pace into the game, saw an 11th-minute shot clip the outside of goalkeeper Joe Wildsmith's far post, and it took defender Tom Lees' intervention to prevent De Jong from converting the Frenchman's 30th-minute cross.
For their part, the visitors grew in confidence with both Marco Matias and Jeremy Helan testing Tim Krul from distance.
McClaren's players returned after the break without skipper for the night Daryl Janmaat, who had taken ill, and Florian Thauvin as Kevin Mbabu was handed a debut and Perez was belatedly introduced.
But Wednesday were looking threatening on the break and took the lead with 14 minutes remaining when the home side failed to deal with a ball into the box and when it broke to McGugan, he drilled it past Krul.
It could have been worse had Krul not turned Lucas Joao's header onto the crossbar with Sergio Bus also hitting the woodwork.
