Preview: Middlesbrough v Accrington Stanley

Middlesbrough coach Aitor Karanka has warned against complacency ahead of his side's FA Cup fourth round tie against League Two outfit Accrington Stanley on Saturday at the Riverside Stadium.

John Coleman"s Accrington are currently 20th in England's fourth tier but have already caused an upset when they beat Burnley in the EFL Cup earlier this season. Acky then nearly took West Ham United to a replay in a later round as well.

As such, Karanka is urging his side not to take this weekend's fixture lightly. He told the club's official website: "I think it's difficult because sometimes you make the mistake of thinking you're going to win easy. 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."

New recruit Patrick Bamford may get the chance to start on his return to Boro after signing from Chelsea. Karanka added: "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."

Meanwhile, Stanley boss John Coleman believes his side stand a chance. He said: "A draw would be good financially for the club as there is the revenue from a replay and you will probably be on television. But it's not in my nature to set up a team like that. I believe when you are going out to play a game of football, whether it's a friendly or against a Premier League team, you should go out to try and win."
