After a goalless first half, Wolves' constant pressure in the second period finally paid off in the 74th minute when Watford defender Francisco Sierralta attempted to clear a cross from a short corner but headed the ball into his own net.

Wolves doubled the lead nine minutes later when new signing Hwang Hee-Chan pounced on a loose ball in a goalmouth scramble to prod home.

The game had been short of goalscoring opportunities but Moussa Sissoko had an early effort on his home Watford debut saved by goalkeeper Jose Sa while Wolves' wing back Nelson Semedo spurned two chances to give the away side the lead.

Wolves, who lost their first three games 1-0, moved out of the relegation zone and up to 13th in the standings, two places above Watford. (Reuters)
