Dundee defender Clark Robertson believes there is "more to come" from Steven Pressley's side as they aim to climb the Scottish Premiership table.
They ended a four game losing run with an impressive 3-1 win over St Mirren last weekend, leaving the Dark Blues ninth in the table, just three points behind city neighbours Dundee United.

"We have probably been inconsistent at times but I think we are growing as a group now," Robertson said.
"I think there is a lot more still to come from us, it is all about having that belief and character about the squad to be able to continue that.'
"We are 15 games in, there is still more than half the season to play so it is vital that we do build on performances like St Mirren and try and back it up with two or three wins on the bounce.

Dundee face a difficult challenge against a Celtic side that look to be returning to form and who have cut the gap on league leaders Hearts to just two points with a game in hand.
However they have already upset the odds against the Hoops once this season and Robertson is challenging his teammates to do so again.
"It is going to take probably a perfect performance again from us," Robertson added.
'There is no reason why we can't do it but we have got to show a lot of belief and character to go and do it."
