Mick Harford has backed Joe Kinnear to be good for Newcastle United.
Harford, who played under Kinnear at Wimbledon, told BBC Sport: "Joe will make a big impact and rediscover the spirit and camaraderie at the club.
"He'll get them organised on the pitch and hopefully pick up some results. The players will enjoy working with him and run that extra yard for him."
Kinnear's Wimbledon side were renowned for their direct and aggressive style of play, yet Harford does not necessarily expect to see this replicated at Newcastle.
"While I was at Wimbledon, we were tagged as a long-ball team, but we also had some of the best players I've ever played with," he said.
"Joe will look at the Newcastle squad, get them organised and get them playing a particular way.
"My message to the Newcastle fans would be 'don't worry. While Joe's there your club is in safe hands'."
