Stoke City midfielder Rory Delap believes his scud throw-ins are "undefendable".
Delap said: "If I throw the perfect ball, with the height and quality of the players in our team, I think it is undefendable.
"It has certainly proved that way in the last couple of games.
"We know what we're doing and it's no surprise. There's no secret to it, everybody knows that we do it but as long as it's working, then great.
"To beat one of the big four makes it that bit more special but we must not get too carried away - we've got to build on this result rather than sit back and take the glory."
