But even with this group of players we are capable of having good defensive games.
Last 10 games for example:
5 clean sheets. Liverpool, Everton, Leicester, Watford, Norwich.
2 games where we only conceded after set pieces. City and Aston Villa.
And three very bad defensive games: West Ham, Palace and SU.
One leader and top CB would do wonders for us.
This is much more essential than Kepa imo.
In this 10 games worst Kepa moments were first West Ham goal after corner and Zaha goal. And for both goals we have at least two players more responsible.
Yes, I would replace him with Oblak or Turkish guy but if we have to choose world class CB is much more important.
