Ferguson raised eyebrows with a number of statements in his book, with his inference that Gerrard is not among the world’s elite the one that has caused the most unrest.
In his book, picked up by the Mirror’s John Cross, Ferguson wrote: "I'm one of the few who felt Gerrard was not a top, top player.”
Liverpool boss Brendan Rodgers took issue with Ferguson earlier in the week and continued the attack following the Reds' win over West Brom on Saturday.
In his post-match press conference, speaking on Sky Sports, Rodgers said: “Steven is a top, top, top, top, top player.”
Jamie Carragher was another to question Ferguson’s views on Gerrard in his column in the Mail, and now Zidane has waded in.
A three-time winner of the world player of the year award, Zidane was one of the finest players of his generation and he has said that Gerrard belongs in the same bracket.
Zidane, per a piece from the Sunday Mirror’s Simon Mullock, said:
For two or three years, Steven Gerrard was the best midfield player in the world.
Even now he is playing at a high level for Liverpool and England.
Alex Ferguson is obviously one of the most successful coaches the game has ever had. But I did find his comments about Steven Gerrard very strange. To say he is not a top player is wrong.
At 33, Gerrard is still operating at a high level. He is captain of his country, and has played his part in Liverpool’s fine start to the season with two goals and two assists, per Premierleague.com.
