Liam Rosenior has indicated he needs to make changes to his Chelsea starting XI after another string of errors against Everton.In similar fashion to their 1-0 defeat against Newcastle United last week, the Blues were undone by a simple ball through the middle in their 3-0 loss.Chelsea were the architects of their own demise at EvertonGettyBeto was on hand to chip the ball past Robert Sanchez, and later hit a powerful strike that sneaked under the goalkeeper for his second.Iliman Ndiaye then scored an excellent curling strike for the third goal after Chelsea lost an aerial battle from a goal kick on 76 minutes.It was their fourth consecutive defeat across all competitions in what has been a nightmare couple of weeks at Stamford Bridge.Rosenior, who talkSPORT’s Rory Jennings believes should be sacked, is facing increased pressure just two months after joining the club.Rose-tinted viewSpeaking to talkSPORT after the match, he acknowledged the errors that his side made and vowed to work on eradicating them.He said: “I take responsibility. I need to pick a team of players in moments that don’t make the costly errors that we’re making, and I also need to help the team do that.“We’ll sit down and analyse how we go about games. We changed the system a little bit, we weren’t so aggressive in our press, I think it actually worked quite well, we had control of the game. “In the moment of the first goal, we looked like the team more likely to score. That’s happened too many times, and that’s something that needs to change.”Chelsea are now off for the March international break, and will return on April 4 to face Port Vale in the quarter-finals of the FA Cup.Rosenior believes the players heading on duty for their countries will be able to take their minds of the club’s form in the next two weeks.Rosenior appears ready to make some changes to his side after their errorsGettyHe remarked: “I think for them, maybe a change is as good as a rest, to get away with their international teams and come back mentally refreshed and refocused may help them.“And it also gives me and my staff time as well. We’ve played, I think, 20 games in ten weeks, something like that, I don’t know the exact number. “But now we have a real, clear amount of time to analyse things, talk and make sure we come back stronger in the run-in.”Everton rub it inWhilst Chelsea and their continued poor run of form makes the headlines, Everton have taken a huge step towards European football.They are only two points adrift off sixth, which would see them reach the Conference League play-off round.Soon after full-time, they made a cheeky dig towards Chelsea with an image of Jake O’Brien holding the ball posted on social media.Everton were the deserved winners at Hill Dickinson StadiumGettyView Tweet: https://t.co/2BaxhnKEZCThe caption read ‘Respecting the ball’, which is a reference to what Rosenior said about his team’s pre-match huddle against Newcastle.It caused controversy as the Chelsea players stood around the referee Paul Tierney on the centre circle.Chelsea have not repeated it since then, although the huddle against Everton was done in close proximity.1: Premier League Fixtures & Results
