Hull

The hosts enjoyed the better of a cagey first half but went behind when Willian swept home a curling shot after good work from Diego Costa after the break.

Costa found the top corner with a similar strike to double the lead after Nemanja Matic's powerful run.

The 18-year-old - making his first appearance of the season - steered home Wayne Rooney's cross to spark wild celebrations on the away bench.

Moments earlier, David Meyler had blazed over in a rare Hull attack.
