Aberdeen are refusing to comment on reports Cardiff City have tabled a third bid for midfielder Jonny Hayes.

The Dons have rejected two bids from Cardiff, two differently structured offers of £500,000, for Hayes, who has 18 months remaining on his Pittodrie deal.

Aberdeen manager Derek McInnes said both offers fell well short of his club’s valuation of the player and urged Cardiff to get serious with an offer if they want Hayes.

Cardiff have reportedly tested Aberdeen’s resolve by making a third offer, this time of £600,000. The Dons say their manager will address the reported offer at his pre-match press conference tomorrow before the Celtic game on Wednesday.

However, Hayes is still at Pittodrie training with his team-mates and it seems unlikely he will be leaving unless the offer is substantially increased.

Bluebirds manager Neil Warnock is desperate to add to his squad before the English transfer window closes at 11pm tonight. The Scottish window closes at midnight.

Cardiff made an approach for another attacking midfielder on Sunday, Blackburn Rovers’ Liam Feeney, but Wanderers manager Owen Coyle rejected the bid for the 30-year-old.
