No its mostly on the keeper.
Whilst i agree our defenders made mistakes
We actually were one of the best teams in the league when it come to least amount of shots conceded
Yet had an abysmal defensive record.
And kepa was historically statistically bad.
On the cb topic im happy for silva for this season and assess next summer.
Not only defensive records but also attacking wise we are among top 3 in creating chances as well. And Lampard done that in first half with mostly two promoted championship players(mount and Tammy) in main starting 11.
Though mount and Tammy did well they are still youngsters and natural up and down in form was inevitable. When they were out of form Chelsea were one of the worst teams to finish of the chances. From December to start of March Chelsea were won just 5 matches from 14 directly collided with Tammy and mount struggling to find form Tammy scored 2 and mount 1 in those periods.
That's why I am so much optimistic about coming season and Lampard with what he has now in his playing staff s ability(Werner,ziyech,havertz,chilwell and Silva) he will do lot better than last season in my opinion.
