Aberdeen sign Kilmarnock's Lyons & Mayo & Austrian Briedl

Aberdeen's summer squad rehaul has started with the triple signing of Lewis Mayo and Brad Lyons from Kilmarnock and Austrian midfielder Alexander Briedl.

Scottish defender Mayo, 26, has signed a three-year contract while Northern Ireland midfielder Brad Lyons, 29 and Blau-Weiss Linz's Briedl have agreed two-year deals.

Stephen Robinson's first summer signings follow captain Graeme Shinnie's departure, with the 34-ear-old midfielder returning to Inverness Caledonian Thistle.

Robinson said Briedl "brings many of the qualities" he wants in a midfielder and that he will be a "good fit" for the Scottish Premiership.

He added that Lyons brings "a real competitive edge and strong leadership qualities" and that Mayo is a player they have "admired for some time" for his consistency and professionalism.
