Leeds United could have wrapped up a deal for Pontus Jansson ahead of the transfer window.
Pontus Jansson has become an instant hero at Leeds United since signing for the club on loan, and signing him permanently has to be a top priority.
Leeds can do so once he has played 20 games for the club, so say terms of the loan agreement, the Yorkshire Evening Post report, for a fee in excess of £3 million.

Prior to the international break, Leeds were on track to wrap this up before the transfer window opened.
Jansson has played in 13 matches for Leeds, and his 20th would have been the Boxing Day fixture against Preston North End.
Now he has missed two matches, the weekend fixture against Rotherham United, and the EFL Cup clash versus Liverpool due to illness.

The earliest Jansson can play his 20th games for Leeds is now January 3, the return game against this weekend's opponents Aston Villa.
Ideally Leeds will be ready to close the deal instantly once he plays the game, but negotiations between the Whites and Torino may not be simple.
With Jansson's future unconfirmed heading into the transfer window, it provides a slither of hope to rival teams hoping to step in and snap him up.
The Yorkshire Evening Post reported that Premier League club Watford are keen on him, and while the centre-back appears adamant he wants to stick with Leeds, closing that transaction has just become a little more complicated than it needed to be.
Smart odds would still say he completes his Leeds switch, but what could have been done and dusted before January will now drag into it.
