Speaking about Morton, Manager Csaba László said, "They have taken the chance as other clubs like Inverness and Falkirk have struggled early season and they are near the top on merit.
"We have to go at them with everything in our pocket, fight and do our job. Football games are like life and sometimes you can be surprised so you must be ready all the time. If you focus you get points and go top. This is my message to my players."
