Angel Rangel says Swansea City and Cardiff City supporters will witness an emotional contest this weekend.
The Welsh clubs will face off in the Premier League for the very first time at Cardiff City Stadium on Sunday and Spanish full-back Rangel suggests it will be a massive occasion.
"I think it's going to be a loud game, really intense and a lot of emotions around," he told reporters. "[The other players] know it's always a crazy one but they haven't experienced it here yet.
"There is extra spice in it and it's going to be really exciting - probably the biggest ever - and the most important thing is to win it."
He added: "It's a derby and the most important thing is to stick together and enjoy it.
"Going to Cardiff is always difficult, we know that, but I don't think it's one you need any motivation for. We know exactly what it means to the fans and to the city.
"We have to play football and try to win it."
