Chelsea will not win the Premier League title this season with Robert Sanchez in goal – they have to sign a new goalkeeper.That’s the opinion of Jamie Carragher and Gary Neville, who think the Blues have no choice but to act in the transfer market.Sanchez made a huge error to hand a goal to Fulham at Craven CottageAFPSanchez started for Xabi Alonso‘s side in their Premier League opener on Monday night, as they beat Fulham 3-2 in a thriller.However, things weren’t all positive in the victory, as the Spanish goalkeeper made a huge error to let in a goal. Fulham’s Josh King burst into the box on the right and unleashed a powerful low strike that headed straight for Sanchez.The keeper was expected to make a simple save, but he instead seemed to dive too late and let the ball through his hands.That has led to some backlash – and speaking post-match, Carragher called on Alonso to make a needed change in goal.Chelsea must drop Sanchez to win titleHe believes that it will be ‘impossible for Chelsea to win the title’ with Sanchez starting and made reference to other successful teams, pointing out that their silverware stemmed from their No.1. “Alisson comes in for Liverpool, they win the league,” Carragher started on Sky Sports. “Arsenal don’t win the league if they have Aaron Ramsdale in goal and not David Raya.“So, one of the biggest reasons why Arsenal won the league last year was Raya, they wouldn’t have won it without him.“You can go back through history and every team that wins the league, 99 times out of 100, the manager has gone and got a good goalkeeper to win him the league.”Neville agreed and added: “It’s a massive personality, a massive character and a great goalkeeper that wins a league title.

But he also questioned the Blues’ defence after they conceded two goals and other big chances to Fulham on Monday.One thing he didn’t have an issue with though, was the attack of Cole Palmer, Morgan Rogers and Joao Pedro, who all scored and combined for five goal contributions in total.Murphy said on talkSPORT commentary from Craven Cottage: “Chelsea’s front line at times was unplayable. Alonso has been told to bring in another goalkeeper to replace SanchezGetty“It’s going to be really difficult, however good your back line is and whatever quality you’ve got there to keep those three quiet.“Because if one of them’s not at it, the other two are more than capable of winning games on their own. “They really are a brilliant three and it’s going to be interesting to see how Chelsea evolve in terms of those wing-back areas because they can have a crucial role in feeding those three.”Murphy then added: “Defensively, there are problems, the keeper’s a problem, of course he is. And I’m not convinced by the three centre-halves after tonight either…“I know they’ve got other players to come back in, but I’ve said it before and I’ll say again there’s not that one standout centre-half who you think he’s the leader.“He’s the one that’s gonna organise the others, he’s the one that, in times of difficulty, he’s the one that will keep us going. He’s the one that will carry us through, calmly get us back into games.“Lots of excitement at Chelsea this season. I think they’ll have games where they’re really hurting score lots of goals, but as for title contenders, no.”
