Posh boss Darren Ferguson went to see the striker, 18, who has scored 11 goals this season, play in the Robins' Conference North defeat at Histon last week.
"We have been made aware of Watmore and we've been monitoring him for a while," Ferguson told the Peterborough Telegraph.
"It was a good opportunity to watch him at Histon and he did well, but we will carry on looking at him for now."
