The Premier League's biggest clubs are keeping tabs on Swansea City goalkeeper Michel Vorm. The Dutchman has been one of the big revelations this season in England.
" A number of clubs have approached us about Vorm," Swans director John van Zweden told VI Radio.
"Manchester United have called, while Chelsea have made an approach as well. Tottenham have also told us that they're interested. Vorm's departure would be a nightmare for us though."
