"It's about attitude and mentality," Vorm told the Swansea Evening Post. "You have to not be afraid to put your foot down because the opposition do that. Most of the other teams are physically stronger than us, but sometimes we have to show that we are not only a team who plays good football."
The Swans again boasted the majority of possession in a Premier League game with their traditional free-flowing passing style and went ahead through Luke Moore.
However, Romelu Lukaku and an own goal by Jonathan de Guzman turned the tie on its head and the goalkeeper is keen for his teammates to show a more aggressive side in future.
"We also have to show the strength and power you need. The whole team need to do it. We have to add a physical element. You could see that we were better than the opposition football wise [at West Brom]," Vorm explained. "It's always us who are on the receiving end of elbows and kicks. We can also do it. It's part of us maturing our game, because teams can't stop us football wise when we play so well even on a bad pitch."
