Middlesbrough are hard at work behind the scenes looking to conclude some key transfer deals, as they look to strengthen their squad further to aid them in what will be a gruelling season. Here's a look at some of the biggest Championship deals that could go through before next month's deadline.
5. Sheffield Wednesday/Cardiff City - Dion Sanderson - IN
The Wolves defender is set to leave the club before the window closes, either on loan and permanent deal. Cardiff had him on loan last season, and want him permanently, but the Owls are very keen too. Photo: Alex Burstow
6. Swansea City - Joe Rodon - OUT
West Ham need a centre-back, and they're having no luck in getting James Tarkowski from Burnley. Rodon looks to be a far more realistic option, and could cost around £15m - a fraction of Tarkowski's asking price. Photo: Jordan Mansfield
7. Watford - Ismaila Sarr - OUT
The club record signing - £40m! - is unlikely to stick about to play Championship football this season, but the Hornets will want at least £35m for him. He could well leave on loan, for the time being. Photo: Naomi Baker
8. Derby/Watford - Jordan Obita - IN
The ex-England youth international was released by Reading at the end of last season, but looks like he could secure a switch to another Championship outfit. Derby and Watford appear to be the front-runners. Photo: Dan Istitene
