Newcastle forwards linked with departure, Sunderland striker search latest plus Chelsea & Liverpool hit the headlines
Serbian international Mitrovic has struggled for gametime this campaign and is keen to leave in order to get regular minutes elsewhere ahead of the World Cup in Russia this summer.
And according to reports the club have knocked back a whole host of loan offers from the likes of Marseille and Brighton for their frontman.
Instead the club prefer to sell the player and use the cash they recoup to strengthen Rafa Benitez's hand this month, as the Magpies battle to beat the Premier League drop this campaign.
Gayle has also been linked with a switch away.
Fulham, who reportedly had two bids knocked back for the player in the summer window, are still keen to add the former Crystal Palace man to their ranks.
Without a suitable replacement lined up, it is unlikely Benitez will allow the No 9 to leave.
Meanwhile, Sunderland are rumoured to be closing in on the capture of Liverpool forward Ben Woodburn.
The 18-year-old was handed his Wales debut by Chris Coleman, and because of that connection the Black Cats appear to have won the race to land the highly-rated youngster.
