Etherington was full of praise for his former manager, who is currently flying high with Crystal Palace.
Pardew took over at Selhurst Park midway through last season and has transformed the club in his time there, with them finishing 10th in the table last term and currently riding high inside the top four.
Etherington worked with Pardew while he was in charge at Upton Park, forming part of the side that lost out in the FA Cup final back in 2006, and he has added his voice to those praising the job overseen by Pardew with the Eagles.
“Even when Alan was having his harder times as Newcastle manager, I have always said that he was one of the best managers I played under,” he told whufc.com.
“As a man-manager he is fantastic. A lot of people have got things to say about him, but he is not that way in any shape or form. He is just a very good Premier League manager.”
With the Eagles soaring, Saturday’s game is likely to be a tough one for Slaven Bilic’s side.
However, their away form has arguably been their strongest asset so far this season, with them having enjoyed impressive wins at Arsenal, Liverpool and Manchester City already.
Those results have got the confidence flowing in the Hammers squad, and Etherington says he is sure they will be arriving for their London derby full of confidence, adding that if they can keep things tight, they have a good chance of collecting another three-point haul.
“I am not surprised to see how well Palace are doing this season. It will be a very tough game for West Ham at the weekend, but I am sure they will go there with a lot of confidence,” he added.
“You look at West Ham's results this season and they are set up to play away from home this season and they are devastating on the break. If they can keep things right they have a major chance of winning.”
