Sky Sports understands Blackpool and Peterborough are both tracking Welling striking sensation Loick Pires.
The 22-year-old is one of non-league football's rising stars and will be out of contract this summer, which is sure to spark a fight for his signature.
He illustrated his qualities again on Wednesday evening by playing an instrumental role in helping Welling gain a 2-1 lead in the Conference South semi-final first leg.
His devastating run from his own half, which left four players in his wake, set up Lee Clarke's winner against Sutton.
Pires has won the club's Goal of the Season award for the last two seasons and was also named their Player of the Year recently.
Welling, however, will be entitled to a compensation fee for the highly-rated talent should he depart the club.
