Wigan boss Martinez pleased with Joel Robles impact
Robles is on-loan at the DW from Atletico Madrid.
Martinez said: "The way we play is the way we want to, and it is something that is going to give us a lot of goals at the other end.
"So I will take responsibility for that. But what I liked to see was the reaction. Football is a game of errors and we had one, but then at the end he (Robles) was magnificent."
