Raheem Sterling’s double and a goal from Nicolas Jackson gave Chelsea their first Premier League win under manager Mauricio Pochettino as they saw off Luton Town at Stamford Bridge.

Sterling, who has started the season in excellent form, picked the ball up wide on the right and jinked his way through three players before firing into the bottom corner in the 17th minute.

The England winger then doubled Chelsea’s lead in the 67th minute when he scored from close range from a Malo Gusto cross.

Sterling was involved again as Chelsea got their third, sending a low cross into the area for Jackson to score his first goal for the club.

Luton, who are still looking for their first points of the season since being promoted from the Championship, caused Chelsea problems throughout the game but the Blues’ quality saw them take all three points

After his £50m transfer from Manchester City, last season Sterling scored nine goals in 38 appearances – his lowest return since his debut campaign with Liverpool.

This season, however, Sterling looks like he is getting back to his best. Pochettino has spoken to the forward throughout this pre-season and the beginning of the campaign as he looks to get the best out of him – which seems to be having the desired effect.

Sterling’s opening goal showed exactly why he is a key part of Gareth Southgate’s England squad when fully fit. He has not been in the past two Three Lions squads because of fitness issues, but it would seem likely that he will be included following his start to this season when the latest squad is named next week.

His second goal against Luton showed his calmness when in dangerous positions, and the pass for Jackson’s goal highlighted his quality.

If Chelsea are to get back to the top end of the table Sterling will be key to their hopes, as he is by far the most experienced and proven attacker they possess.
