The Leeds boss was frank with the Swiss defender but has been taken aback by his performances.
The 52-year-old admits he was honest with the defender - but now thinks he was wrong.
Indeed, the Leeds boss feels Berardi was outstanding against Bolton at the weekend and says it's no surprise he's represented Switzerland.
Evans was speaking after United's 1-1 draw at Bolton on Saturday afternoon, one that leaves the Whites 17th in the Championship table.
Evans is quoted as telling reporters: "I said to him that before I came here I didn’t think much about him. I was honest with him but he was outstanding. It’s no surprise that the boy has played for his country."
Berardi's form has gone under the radar somewhat during his Leeds career. The Swiss didn't get off to the finest of starts at Elland Road and soon became synonymous with the words 'red card.'
However, the 27-year-old hit form at the end of last season and slotted into Neil Redfearn's first team seamlessly.
This term, he has continued performing. And, although Sam Byram will be thought of by most as Leeds' best right-back and Charlie Taylor the club's best left-back, Berardi's contribution hasn't gone unnoticed among fans so far this term.
Evans has now taken notice after just two games. How should he utilise Berardi's versatility?
