Watkins ended the campaign with a flourish, scoring eight goals in his final eight Premier League matches, while also lifting the Europa League trophy.
The 30-year-old hit a purple patch of form at the right time to earn a place in Tuchel's 26-man squad after finding the net just once in nine top-flight matches between January and March.
Ready to play second fiddle to the unstoppable Harry Kane, as he did brilliantly two years ago at Euro 2024, Watkins arrives in North America full of confidence.
A return of 26 goal involvements for Aston Villa last term showcases his impact during their trophy-winning campaign, and he could do similar from the bench for England.
But for all of his top striking qualities, Michael Owen believes he is "too nice", and to become even better, he's got to be "ruthless" and "horrible" on the pitch.
"So, what’s the secret to unlocking Ollie? The problem with him - and I tell him this all the time - is that he's too nice," Owen wrote in his Daily Mail column.
"He's the nicest man in the world! To be a top centre-forward, and truly rip the guts out of your opponents, which you have to want to do, you've got to be a bit horrible on the pitch.
"You’ve got to be ruthless. You’ve got to have an edge. Off the pitch, you can be lovely, and he is. But when you cross the line, you've got to be brutally clinical."
Watkins has often showcased inconsistency with his finishing, but when he steps onto the pitch for England and gets that chance, he has to take it.
