Middlesborough

Steve Agnew's side knew that a defeat at Stamford Bridge would result in their return to the Championship after just one season in the top flight and they proved unable to avoid that fate, marking the fourth time they have been demoted from the Premier League.

First-half goals from Diego Costa and Marcos Alonso left Middlesbrough with a huge task and there was to be no miraculous fightback, Nemanja Matic extending the league leaders' advantage after the break.

Diego Costa gave the hosts the lead after 23 minutes at Stamford Bridge, recording his 20th league goal of the season.

Marcos Alonso soon doubled Chelsea's advantage and Nemanja Matic completed the scoring after the interval to wrap up a comprehensive victory, relegating Middlesbrough in the process.

Chelsea will now be crowned champions for the second time in three seasons if they win at West Brom on Friday after picking up a maximum three points for the 15th time at home this season.

Antonio rose highest at the back post to head in Gokhan Tore's cross and decide a game of few chances.

The goal came eight minutes after Bournemouth's Harry Arter was sent off for a second bookable offence.

Cherries goalkeeper Artur Boruc saved well from Enner Valencia in the first half, while Adrian denied Joshua King.

A club-record 56,977 supporters were in attendance as West Ham played their first league match at their new home, having left Upton Park at the end of last season.
