Middlesbrough and Leeds United lock horns at the Riverside Stadium this afternoon, in what should be a hard-fought battle on Teesside.
Boro entered the season as Championship title favourites, and with four league wins in a row, Aitor Karanka's men are firing on all cylinders.
Karanka has named a strong attacking line up, with Albert Adomah, Stewart Downing and Christian Stuani supporting David Nugent in attack, whilst former Leeds midfielder Adam Clayton starts in midfield.
As for Leeds, manager Uwe Rosler has brought Giuseppe Bellusci in to the line-up in place of Liam Cooper in central defence, whilst Mirco Antenucci leads the line, with Chris Wood missing out through injury.
Winger Jordan Botaka will make his first appearance for the club since his deadline day move from Dutch side Excelsior, with contract rebel Sam Byram left on the bench, as predicted.
