Middlesbrough boss Aitor Karanka: Leeds United clash will be "very tough"

Middlesbrough boss Aitor Karanka has admitted that his side will face an extremely tough task in their Championship clash against Leeds United.

The North-East outfit have won their last five matches on the spin in all competitions, including their 3-0 triumph over Wolverhampton Wanderers in the Capital One Cup in midweek.

Karanka has failed to beat Leeds in his time with Boro and believes that they will continue to be a tough team for him to crack, especially with Uwe Rosler in charge.

He told Sports Mole: "They've been working with Uwe throughout pre-season and I felt for that reason that they are going to be a difficult team.

"He's very organised and has been working with them for three months, so it's going to be a very tough game for us."

The Spaniard added in his pre-match press conference: "Leeds are a team who are always difficult to play. I have never beat them. I'm working in the way that I always work."

Middlesbrough take on Leeds at the Riverside Stadium on Sunday.
