Dier made a mistake on Sunday, it happens ffs. He was immense alongside Dembele against United.
Pochettino rates him so highly because he's so reliable in terms of his mentality, a complete competitior who has been instrumental in us losing that soft underbelly we had for years.
He's also tactically flexible and Pochettino trusts him.
Some are way too critical of him. He's not perfect but still a very important cog in this side.
We would have lost by at least two goals against southampton due to dier's dire passing in our own half. We did not lose because they were very poor in the finishing department.
