Fergie questioned Bolton's motivation ahead of Sunday's trip to Chelsea after hearing of their survival celebrations last Monday.
"Sometimes it is a good thing it gets everybody together, Sir Alex was just making sure the players were on their toes and they were.
"I received a text from him the other day I text him well done and he text me back well done and hoped his team talk did not upset the players
"It didn't it never did. They put in a real good shift down there to get a draw at Chelsea which most people haven't done they worked their socks off."
