Hughes played primarily as a central defender for several clubs, including Falkirk (two spells), Celtic, Hibernian and Ayr United.

Towards the end of his playing career, Hughes took on coaching responsibilities, and was appointed manager of Falkirk in 2003 (initially as co-manager with Owen Coyle).

He subsequently played for his local club Hibernian, Ayr United and finally returned to Falkirk in a joint player and coaching role.

[3] He famously performed a streak during his first stint at Falkirk whilst team-mate Mo Johnston was being interviewed for STV's Scotsport.

Coyle subsequently left Falkirk to join Ian McCall at Dundee United, leaving Hughes in sole charge.

[13] Hughes was appointed manager of Scottish Premiership club Inverness Caledonian Thistle on 4 December 2013 on a two-and-a-half-year contract.

[14] Soon after this appointment, Hughes led Inverness CT to their first major final after beating Hearts in a penalty shoot-out in the semi-final of the 2013–14 Scottish League Cup.

At the beginning of season 2014–15, Caley Thistle's excellent early performances led him to receive the award of SPFL Manager of the Month for August.

[16] In April 2015, Hughes led Caley Thistle to their first ever Scottish Cup final after a controversial 3–2 win over favourites Celtic, and at the end of the month he was shortlisted for PFA Scotland Manager of the Year.

[17] On 3 May, Hughes was announced as the winner of the managerial award ahead of Ronny Deila, Derek McInnes and Robbie Neilson.
