Andy Murray's former coach Miles Maclagan believes that the British number one will experience a slump in results as opposed to a surge of victories after picking up the US Open trophy.
The Scotsman secured his first Grand Slam title in a dramatic five-set thriller against Novak Djokovic at Flushing Meadows last night.
"[Murray is] in uncharted territory and he could go one of two ways," Maclagan told BBC News. "Either he'll absolutely fly for a while and win everything in sight but it wouldn't surprise me to see a bit of a lull.
"You reach a lifetime goal, something you've strived for your whole life, and you've now got it and you have to take a bit of time to think I've got to set some new goals readjust myself and build up some determination for that."
Murray became the first Brit to clinch a Grand Slam title in 76 years.
