Qureshi told the Sunday Mirror: "It was brilliant watching Sam work.
"The picture I had of him was a big bloke angrily stomping up and down by the dugout barking orders, but it couldn't be further from the truth.
"He will clamp down on a player when he needs to do, but he is far more likely to put an arm around a player and have a quiet word.
"He's very much a psychologist himself.
"He realises and understands the power of rapport with his players to get them on his side and he does it with humour not anger."
