Glasgow: Celtic manager Ronny Deila says Stuart Armstrong and Gary Mackay-Steven are finally settling into life at the Glasgow giants after they scored the goals that sealed a 3-1 win over St Johnstone on Saturday. The midfield pair, who made a blistering start to their Celtic careers with goals on their debuts following their transfer from Dundee United last January, have seen their development at Celtic Park stall this season due to injuries and a loss of form. However, a double from Mackay-Steven and a solitary strike from Armstrong saw the Hoops restore their six-point advantage over Aberdeen at the top of the Scottish Premiership table.
