Motherwell boss Stuart McCall hailed his side's professionalism as they routed Morton 6-0 to reach the quarter-finals of the Scottish Cup.

The home side stunned their First Division opponents as they raced into a 5-0 half-time lead.

Tom Hateley netted directly from a corner before Jamie Murphy, Shaun Hutchinson, Henrik Ojamaa and Nicky Law all netted for the hosts as the tie was all-but decided before the interval.

Murphy then blasted home his second midway through the second half to add to Morton's woes and complete a one-sided scoreline.

"It was a professional job, we asked at the beginning of the game for a high tempo as we couldn't afford to go out and take liberties or we would be in for a rude awakening," said McCall.

"We started well and got the goal directly from a corner which was quite unusual.

"I asked the lads not to take their foot off the gas and psychologically that sometimes happens. Credit to Morton, they stuck to the task."

Victory over Morton ensured Motherwell have now won their last three home encounters, notching 12 goals in the process.

After going almost four months without a win on home soil, McCall believes his side have now turned the corner.

"We had a meeting after the Dundee United game and spoke about three massive home games. We have achieved our aim and managed to win all three games, scoring 12 goals," added McCall.

"We have played our best football at home, the confidence is high and hopefully we have addressed our poor home form."

Morton boss Allan Moore admits he felt sorry for the team's fans that travelled to Fir Park for their Scottish Cup hammering.

"In the first half we didn't do our job correctly. The guys weren't picking up and they lost four goals from dead-ball situations," said Moore.

"At half-time I was worried and worried for the players, but in the second half we knocked the ball about a bit better and had a few shots on target.

"It's a sore one to take, the fans have spent money in coming to watch us. At half-time I was pleased that some of them had stayed as it was a painful day for everyone."
