Hull made a dream return to the Premier League after a nine-year absence, beating Manchester United 2-0 on Saturday to puncture any preseason optimism surrounding the 20-time champions. First-half goals from Semi Ajayi and Nobel Mendy at set-pieces consigned United to a tepid loss to a team that was promoted via the second-tier Championship playoffs at the end of last season and is widely expected to be among the relegation candidates.
