Middlesbrough have made an improved offer for Fulham striker Ross McCormack, Sky sources understand.
Fulham turned down £6m for McCormack last week but Aitor Karanka has now tabled a second bid, believed to be of £8m plus Spanish striker Kike, for the Scotland international.
Boro boss Karanka is a long-term admirer of McCormack, who has scored 17 goals in 31 appearances in all competitions this season.
Fulham, who appointed Slavisa Jokanovic as their head coach last month, are under a transfer embargo and reluctant to sell McCormack.
Jokanovic said earlier this month: "I am not thinking about selling my key players like McCormack or Moussa Dembele. I don't plan for it and that's it."
McCormack, who joined the Londoners from Leeds for £12m in 2014, has also been linked with other Championship clubs.
Sheffield Wednesday reportedly failed with a £10m bid for the 29-year-old in the summer.
