Actually Steven Gerrard was quite good when he was Rangers coach even though he won the title in his third season at the club but unfortunately, he chose to accept Aston Villa's offer which was the beginning of his coaching career being tarnished because in the end he was fired, many advised him to stay in the league Scotland to gain experience before accepting offers from other clubs in leagues such as the English Premier League, where the competition is tighter compared to other leagues, but for Wayne Rooney or Frank Lampard and also Graham Potter, it cannot be denied that they are quite bad coaches even though Potter is still better when he was at Brighton.
Maybe clubs want to make Steven Gerrard, Wayne Rooney, and Frank Lampard become coaches, seeing that their success as players can also be demonstrated when they become coaches, unfortunately, that hasn't happened at least for now.
