Royle is aware that the country's leading scorer is the main threat against his Tractor Boys.
"He is a good old-fashioned goal machine, and we will have to be on top of our game all the while to stop him adding to his tally.
Royle finished by talking his team up.
"We are strong and confident at the moment, and getting stronger. We are the division's leading scorers, and opponents are aware that they may well have to score three times at least to beat us."
