Ayoze Perez, Chancel Mbemba and Dwight Gayle scored in a comfortable victory, but it was Jack Grealish's 89th-minute equaliser for Aston Villa at Brighton which sealed the Magpies' title.

Perez's flicked finish made it 1-0, before Mbemba smashed in to double the lead from a Perez rebound.

Gayle added a late third before Grealish's goal handed them the title.

It was a comfortable win for Rafael Benitez's side - yet it looked like it would not be enough to seal top spot, after Glenn Murray's penalty had put league leaders Brighton in front at Villa Park.

However, despite being down to 10 men following Nathan Baker's red card, Grealish beat Brighton keeper David Stockdale to send the Magpies above Brighton in the table.

At St James' Park, DeAndre Yedlin terrorised Barnsley down the right-hand side and it was his cross which Perez guided into the bottom corner to open the scoring.

Christian Atsu forced Barnsley goalkeeper Adam Davies into two strong diving saves with powerful shots and Massadio Haidara smashed a good chance over the crossbar from Perez's cut-back as the hosts dominated.

Davies kept out Jack Colback with his legs, but the Magpies got a deserved second when Davies pushed Perez's shot out perfectly for Mbemba to smash home his first goal for the club.

Jonjo Shelvey struck the post before Aleksandar Mitrovic's header sent substitute Gayle through to complete the scoring with a confident finish past the onrushing Davies.

Atsu, 25, who is on-loan from Premiership leaders Chelsea was joined on the pitch by his young family for the celebrations.
