Coyle plans to repay him by ending Tottenham's Wembley dream at White Hart Lane tonight.
Coyle said: "It doesn't surprise me because I know the man he is anyway, but I've spoken to Harry two or three times a day since last week.
"That was while I was down there. But even when I came back and we both had games to prepare for, I spoke to him each day. That just sums up the man he is.
"He didn't have to be phoning two or three times a day for an update, but he had genuine concern and goodwill.
"From Daniel Levy as chairman all the way through the club, Tottenham Hotspur have been truly outstanding."
