Aitor Karanka has warned his Boro side to not take this weekend's fixture lightly when Accrington Stanley arrive at the Riverside.

John Coleman's Accrington are currently 20th in League Two but have already caused one upset this season when they beat Burnley in the EFL Cup, before almost taking West Ham to a replay in the following round.

Stanley also knocked Boro out of the League Cup on their last visit to the Riverside, but Karanka is confident that his side can progress in the Emirates FA Cup on Saturday.

"I think it's difficult because sometimes you make the mistake of thinking you're going to win easy," said the Boro Head Coach.

"The best reference for us is to look at their game against West Ham. 

"They made it very difficult for West Ham to beat them but if we go to the pitch knowing and showing that we're better than them then we'll win the game."

Patrick Bamford made his first appearance since re-joining Boro in last weekend's game against West Ham and Karanka says the Accrington game will provide the perfect opportunity for the striker to get more valuable minutes under his belt.

"He'll be involved, for sure," said Karanka when asked if Bamford may feature. 

"I don't know whether it will be for 90 minutes, 70 or 45 but if he picks up no injuries on Friday then he will play. 

"It's a good game for Patrick to play in, at the Riverside in front of our crowd. He was really important to us in the past and I'm sure he will be important in the future."
