The Gers will take on Hibernian in the final of the prestigious cup competition at Hampden Park in Glasgow later this month.
Mark Warburton’s will not have played a competitive match for three weeks when they take on Hibernian.
McKay, who is just 21 years of age and has had a productive season, has made it clear that the players are training hard and are focused on the match.
“I suppose it's only natural there should be a dip in form after the high of reaching the Scottish Cup final but we certainly didn't want it,” McKay told The Daily Mail. “It just happened. But every session we have between now and the final will be high intensity because we train at the same tempo as we play.
“We won't lose our edge in the next three weeks because we've got a great bunch of boys. On the park, we all trust each other and the manager trusts us to do the right things off the park and we need to show professionalism by not going out every night.”
McKay’s comments show that manager Mark Warburton is determined to win the season on a high.
Rangers won the Scottish Championship title with ease this season and gained automatic promotion to the Scottish Premiership.
The Gers have also won the Scottish Challenge Cup, and clinching the Scottish Cup will see them claim the treble.
McKay’s comments should be welcomed by the fans, who can rest assured that the Rangers players will do all they can to win the Scottish Cup final.
