Michael Vorm says his pre-match research helped him massively after saving Ben Watson's penalty in his side's 0-0 draw with Wigan. Vorm produced a superb second-half save to secure the Swans' first ever Premier League point in what was an otherwise decidedly average match at the Liberty Stadium. Watson previously scored from the penalty spot on the opening day of the season and when quizzed about the incident, the Dutchman said he'd watched the penalty and believes this gave him a huge advantage against the former Crystal Palace man."Last week also the goalkeeper went to the same corner and he shot it very well," said Vorm. "The only thing for me was trying to concentrate and go at the right moment to the corner."He shot it low so I could get my hand to it. It was a good save I think."
