​Steven Pressley has praised his centre-half pairing of Owen Bevan and Ryan Astley for providing the foundation for Dundee’s solid start to the season.Welshman Astley, an Everton youth product, and Bevan, who joined the club from Bournemouth this summer, have formed a formidable partnership.They were key players once again as Dundee beat Motherwell 2-1 on Saturday to move up into fourth place in the Premiership table on 10 points.However, former Scotland defender Pressley is still demanding more from the duo.The Dundee boss said: “I felt this was a big game because I remember going into the international break last year after a 4-0 loss to Aberdeen.”So you have to enjoy a result like this, particularly with the transition of players and the injuries we have. We are still trying to find our rhythm.”Ten points is not a brilliant return but it’s a very solid start for us. There is more to come from us and that’s what makes me excited.”Bradley Fink added to Joe Westley’s penalty in Saturday’s win. Alex Lowry pulled on back but Bevan, Astley and their defensive colleagues otherwise saw the game out well.Pressley added: “The centre-halves have been outstanding since day one and are developing.”Astley has been with us for 14 months and has really grown in stature.”Owen is developing well but I want to see a bit more leadership from them. I want to hear them talking more and that’s the next phase of their development – communication and leadership.”But it will come with time and age, and we need that as a team at present. We need more leadership and I want a lot of people to grow into that role.”I want many leaders and we will keep working on that.”
