Peterborough supporters at the ABAX Stadium this weekend may well have thought Willem Tomlinson was a seasoned professional after an accomplished second half display from the youngster in the 2-3 win.
But Rovers fans will have known that Tomlinson was making his first league appearance of the campaign, after replacing Corry Evans at the break.
Willem produced a mature performance in the heart of the Rovers midfield and boss Tony Mowbray was certainly impressed with the 19-year-old's display
"I thought he was fantastic really, considering he's been out of the picture for a lot of this season," Tony told iFollow after the game.
"When I arrived here Willem was in the team. He almost fell through the cracks in a way, spending time on the bench and missing the Under-23s and lacked fitness.
"He's trained so hard this season and produced the goods for the Under-23s this term as well."
And the boss wants Willem to seize the opportunity now and kick on from his weekend performance.
It's likely the teenager will be needed too, with both Peter Whittingham and Corry Evans being forced off with injury.
"It's up to him now to try and make it hard for the likes of Whittingham and Evans to get back in the team," Tony added.
"There are no favourites with me. Whether you're Peter Whittingham, who's played 400+ games in the Championship or Corry Evans, who has represented his country at European Championships.
"Willem's performance gives me encouragement. He has got to try and be the best player. He has other young lads coming through in his position such as [Lewis] Hardcastle and young Rekeem [Harper], so it's up to him to keep the shirt."
