Midfielder Flood was again instrumental as new boss Jackie McNamara made it back-to-back victories with a 3-1 win over Hearts at Tannadice on Saturday.
Flood notched a quality second goal in the second half as new manager McNamara watched his side move into sixth place in the SPL thanks to Johnny Russell's second-minute strike and substitute Michael Gardyne's 89th-minute clincher.
Flood has been given a new lease of life since McNamara replaced departed boss Peter Houston recently, and Tangerines team-mate Mackay-Steven was quick to sing his praises after beating the Jambos.
He said: "Willo has been outstanding for us in the past two games.
"His goal was quality and his overall performance was of the highest order.
"Willo is big player for the club.
"He's the one who really gets everyone up for training every day and urges them on.
"Willo expects the highest standards from those around him and he's always there to do his bit as well.
"He looks as though he's really enjoying his football right now and long may that continue, along with the rest of the lads."
