Arsenal hero Martin Keown says Tottenham must be wary of Sheffield United's attacking tactics in tonight's Capital One Cup tie.
Keown wrote in the Daily Mail: "United have a variety of players capable of playing on the wing, but they all have one thing in common - they are happy to sling in crosses from every angle.
"Jamie Murphy likes to push upfield and cut inside to cross with his right foot and Ryan Flynn, who has played on the wing and at full back this season, is a bag of tricks down the right.
"Louis Reed became the youngest player to play for United in the league last year and, at 17, is a talented youngster, while Jamal Campbell-Ryce is another rapid wide man.
"Clough says top-flight teams struggle with United's crosses but it's more to do with the number of men who are prepared to fly forward and get on the end of them.
"In the Premier League, defenders are used to playing against lone strikers with maybe another runner off the front into the area.
"The reason the likes of Southampton and QPR have found it tough against United is because they pile people forward."
