Everton manager Marco Silva has called on the club to "stick together" after falling to a dramatic 3-2 defeat at Brighton & Hove Albion on Saturday.

After trailling 1-0 to Pascal Gross' 15th-minute opener, Everton struck back through an Adam Webster own goal five minutes later.

Substitute Dominic Calvert-Lewin gave Everton the lead, and with 16 minutes remaining, the visitors would have expected to leave the Amex Stadium with at least a point.

Instead, Neal Maupay levelled for Brighton with 10 minutes left after VAR awarded a penalty for a contentious foul by Michael Keane on Aaron Connolly.

Then, deep into stoppage time, Lucas Digne scored an own goal to gift Brighton the win and increase the pressure on manager Silva, who was not pleased with the use of VAR in awarding the penalty while denying Everton one of their own.

"If VAR saw something in our box, why didn't it see 15 minutes earlier the penalty for Richarlison," he told the BBC. "Because of that my players are in the dressing room and don't understand.

"If they see one for one side then they have to see for the other side too. It was a clear penalty [to us]. VAR has to be the same for both sides."

The defeat leaves Everton down in 16th place, and Silva believes the squad can turn around their fortunes.

"We have to be more mature to control the last 10 minutes. It's a tough moment for us. We have to stick together," he said.

"We conceded the first goal but after that we reacted strongly and as a team. We created some dangerous moments."

Brighton manager Graham Potter paid tribute to his players' fighting spirit, saying: "To turn it around like we did is an amazing feeling. It was an important moment to get the equaliser and there was a feeling in the stadium for us to push on and get the win."

West Ham's winless run was extended to four Premier League games after Sheffield United earned a 1-1 draw at the London Stadium.

Robert Snodgrass put the hosts in front just before half-time, before Lys Mousset struck in the second half to earn the promoted side a point.

"In football you must score. We dominated the game and tried to create options to score," West Ham manager Manuel Pellegrini said. "I am happy with the attitude of the team. Today we had the feeling we can do it better because we dominated part of the game and had chances to win it."

Watford's search for their first win of the season goes on after the bottom side were held to a goalless draw at Vicarage Road.

In the day's late game, Christian Pulisic made the most of a rare start by scoring a perfect hat-trick to lead Chelsea to a 4-2 victory at Burnley.

The American winger, a summer arrival from Borussia Dortmund having signed for the club in January, scored twice in the first half and completed his treble by flicking home a Mason Mount cross 11 minutes after the interval.

Willian then put Chelsea in total control two minutes later with a fine finish.

Burnley then struck back with one of the goals of the season so far as Jay Rodriguez hit an unstoppable long-range strike in the 86th-minute. Dwight McNeil pulled another goal back for the hosts with a deflected effort three minutes later, but the barrage from Burnley came too late.
