Dean Sheehan, who's agency represents the player told the Western Mail
"The player jetted in from Iceland on Sunday and is due to speak to Cardiff early this week.
"He will have a good look around the football club with a view to playing for City. He has heard of Lennie Lawrence's reputation as a coach and he is convinced that is game can advance under his guidance.
"But we have been speaking to City about Gylfi since September 1. We are keen to see him settled in the UK. There is no criticism of Cardiff, but Leeds have stepped into the equation.
"Whoever gets Einarsson will grab a steal because when he proves himself in the Championship you'll be looking at a £1m-plus valuation - at the very least."
