Hearts have made an official approach to Kilmarnock after targeting Derek McInnes for their managerial vacancy, the PA news agency understands.
McInnes looks destined for Tynecastle after three and a half years in Ayrshire.
The former St Johnstone, Bristol City and Aberdeen manager led Killie to the Championship title and then back into European football and they secured their William Hill Premiership safety on Saturday.
Speaking on Sunday, McInnes said on Sky Sports: “I’m hearing that there may be contact between the clubs, but there’s been nothing official yet from my point of view.”
