Chelsea staged an impressive fightback in the second half to beat Aston Villa 2-1 as Olivier Giroud's winner consolidated their place in the Premier League's top four. The Blues were rocked when Kortney Hause put Villa ahead against the run of play in the first half. But Christian Pulisic came off the bench to equalise after the break before Giroud bagged his fourth club goal of the season two minutes later. Chelsea's quick-fire blitz moved the fourth-placed west Londoners five points clear of Manchester United in fifth in the race to qualify for next season's Champions League. Liverpool need favours from Manchester City to clinch a first Premier League title in 30 years this week after being held to a 0-0 draw by Everton in a Merseyside derby without the usual fervour behind closed doors. Everton came the closest to breaking the deadlock as Tom Davies struck the post and Alisson Becker saved from Dominic Calvert-Lewin to deny the Blues a first derby win in 10 years. Liverpool remains well on course to win the league with a 23-point lead over Manchester City at the top of the table.
