The British newspaper has reported on its live transfer feed at 8:11am on Monday that a number of scouts watched the 18-year-old midfielder in action at the weekend.
The England Under-19 international featured for Leeds in their FA Cup fourth-round tie against Bolton Wanderers away from home at the Macron Stadium. The youngster played virtually the entire game and helped his side win 2-1.
While clubs may try to sign Cook today, one suspects that Leeds are unlikely to sell him. The 18-year-old is one of the best and most promising young players in the Championship, and he would be a massive loss for the West Yorkshire outfit.
A replacement for Cook would be very hard to find so late in the transfer window, and the likelihood is that Leeds will reject all offers for the teenager today.
