Chelsea loanee Patrick Bamford starred in a famous 2-0 win as Middlesbrough stunned Manchester City in the FA Cup fourth round.

The Championship’s second-placed side absorbed sustained first-half pressure, with normally second-choice goalkeeper Tomas Mejias making a string of impressive saves at the Etihad Stadium.

And Middlesbrough’s resilience was rewarded as City produced some shambolic defending for Bamford to strike in the 53rd minute.

Aitor Karanka’s team almost doubled their lead when the excellent Lee Tomlin struck the post before substitute Kike sent a packed away end into raptures by sealing victory in injury time.

City, who arrived back in Manchester on Friday evening following a training break in Abu Dhabi, appeared jaded as their performance unravelled.

Frank Lampard came off the bench to strike the post after 89 minutes but back-to-back, scoreless home defeats means manager Manuel Pellegrini and his players head into next weekends pivotal clash at Bamford’s parent club with a season to salvage.

The visitors made a confident and stylish start, though they were almost undone in the fifth minute when Stevan Jovetic was inches away from converting Aleksandar Kolarov’s cross.

Middlesbrough had the ball in the net after 19 minutes – Lee Tomlin heading home after Willy Caballero kept out Bamford’s flick – but the latter was penalised for offside.

Sergio Aguero’s first sight of goal arrived five minutes later as his skipped around Ben Gibson to drill into the side net
