Evans came through the ranks at United and went on to play almost 200 matches for the club, winning three Premier League titles.
The former Sunderland loaner traveled to West Bromwich Albion in 2015 after struggling for playing time under Louis van Gaal.
Evans has since performed at a high level for Leicester City, where he has played 117 times and won the FA Cup since signing on a £ 3.5 million move in 2018.
United have spent heavily on key defenders such as Harry Maguire, Victor Lindelof and Eric Bailly, but have still had difficulties in their backline in recent times.
Five years later, Souness still does not understand the sale of Evans, who he feels is better than all of their current center-backs.
“I look at Manchester United without having any inside details on how they work,” Souness told talkSPORT.
“I do not see anyone raising their hand and saying ‘I signed him, he is my player’.
“I do not see anyone taking responsibility. What you need to be right in a football club is recruitment, and since Fergie left, it’s been a master class in how to get it wrong.
“This is how I see it. You look at the players they have brought in, the players they have sold.
“Jonny Evans was allowed to go. Jonny Evans is better than any center-half they have now. I just do not get it. “
Evans was well-liked by Sir Alex Ferguson, who was surprised that Evans was relieved by United after Rio Ferdinand and Nemanja Vidic.
Northern Ireland manager Michael O’Neill recalled: “There was a conference in France for the coaches and Sir Alex spoke about it and he said openly to me that he could not believe Van Gaal had sold Jonny from United because he had seen him come. through, he felt that Jonny would spend his entire career at United or certainly to the final stages of his career. “
Souness described Anthony Martial and Juan Mata in the same interview, just as he struck out with the appointment of Ralf Rangnick as interim chief.
