Football news - Substitutes Andone and Maupay wrap up win for Brighton at Watford

And fellow replacement Neal Maupay - on for Glenn Murray and making his debut - added to Albion's tally when he raced on to a through-ball and slotted past Ben Foster in the 77th minute.

The visitors had gone 1-0 up in the first half when Abdoulaye Doucoure turned Pascal Gross's cross into his own net.

Andone replaced Jurgen Locadia just after the hour mark, and smashed home Davy Propper's ball from close range to confirm the victory - just how new manager Graham Potter will have dreamt of starting the season.

Playing in a new formation with three central defenders and wing backs, Brighton looked a more attacking team compared to last season.

"We've been working really hard to play this way... it's just the start of the season... the boys are behind the manager and agree with his ideas," Maupay told the BBC.

Fellow goalscorer Andone said that Brighton were delighted to dish out an early upset, having lost 2-0 to Watford in their league opener last season.

"I didn't expect that... it was an unbelievable match. We did well. It is out first time playing with five defenders," the Romanian added.

"We did perfect, from the beginning to the end, and we have to enjoy the match."

Brighton will look to continue their bright start when they host West Ham United in their next match while Watford face a potentially tricky test at former boss Marco Silva's Everton.

Watford manager Javi Gracia said his team had no excuses after making too many errors.

"What I know is they played better than us and deserve the victory. No excuses... we try to improve for the next one," the Spaniard added.

"The best news is that it's the first game. Sometimes it's good to wake up and improve. We need to do that. There were many individual mistakes."
