Manchester United were not the only Premier League side to suffer Capital One Cup humiliation as Burnley, Leicester and West Ham made early exits.
City were undone 1-0 by Shrewsbury Town at the King Power Stadium, Andy Mangan scoring the winner seven minutes before half-time with a free-kick for the League Two side.
Burnley, like Leicester newly promoted to the top flight, were beaten 1-0 by Sheffield Wednesday at Turf Moor. Atdhe Nuhiu got the winner with a 78th-minute penalty after defender Jason Shackell had fouled Jeremy Helan in the box.
Sean Dyche’s side had been in the ascendancy at the time but the contest overall was fairly even and the visitors had gone close when Burnley’s Kevin Long struck the frame of his own goal.
West Ham lost on penalties at home to Sheffield United after the game finished 1-1 after extra time.
Bafétimbi Gomis scored his first goal for Swansea as they saw off Championship side Rotherham 1-0. The 29-year-old slid a shot past Scott Loach after a neat turn inside the box to put the Premier League side ahead.
League One Doncaster won 1-0 at Championship side Watford. Rovers took the lead with a Nathan Tyson penalty on 12 minutes after a Kyle Bennett foul. Watford equalised through Lloyd Dyer on the half-hour but Liam Wakefield popped up with Rovers’ winner on 51 minutes.
Fulham got their first win of the season, 1-0 at Brentford, thanks to a goal from £11m signing Ross McCormack, his first for the club.
