HULL City will hope to find a breakthrough in negotiations for top target Charlie Austin in the next 48 hours after leaving Burnley to mull over a final "take it or leave it" offer.
The Tigers returned for pre-season testing this morning with manager Steve Bruce still searching for a new attacking threat to spearhead their Premier League return next month.
Burnley striker Austin and Celtic forward Gary Hooper have both been the subject of failed bids in recent weeks, but City are still pushing hard to prise Austin out of Turf Moor.
Sources have told the Mail that City have returned with an improved offer this week, believed to be in excess of £4m, and will not be pushed higher.
Burnley, who have valued their prized asset Austin at £7m this summer, are yet to respond to the Tigers' latest approach, but City will hope their persistence finally pays off.
Bruce's frustration means he will not discount a fresh move for Hooper, but if he is able to land Austin his search for a second striker will be focused primarily on the loan market.
