The Aston Villa man is with Gareth Southgate’s squad for the first time at the competition in France and enjoyed a successful full debut on Monday, scoring twice in a 7-1 win over Guinea.
And after suffering the disappointment of relegation and an injury-hit campaign at Villa Park this term, Grealish is hoping to salvage something from the season in Toulon.
"I think it was good for me to come here, and hopefully end it [the season] on a high and maybe win something to then bring that confidence into next season," he told FATV from the team’s base near Bandol.
"I’ve not had the best of seasons at Villa, I haven’t been playing as much as I wanted to after doing my ankle a few times.
"I didn’t really expect to be called up, but the gaffer has done and it’s been good. I’ve enjoyed my time here and the ambition now is to keep playing regularly with my club and England and hopefully my future will be to go on to play for the senior side.
"I think Duncs [Watmore] is a good example, he came here to Toulon last year for his first England trip, he did well and it brought him through into the first team at Sunderland and he also staked his claim here.
"It’s a good chance to show what you’re capable of and prove yourself."
It didn’t take the Solihull-born schemer long to settle in after the squad first met up at St.George’s Park last week.
After just two training sessions there, it was off to Provence for the competition and following a substitute appearance in the opening win over Portugal before Monday’s first start for the Three Lions, the former Notts County loanee admits he’s enjoyed every minute so far.
"It’s been good, I get along with all of the boys and the manager’s been brilliant since I came in," he added.
"He’s made me feel welcome and gave me a chance against Portugal and a chance against Guinea so hopefully I can repay him.
"I think we can definitely go on to win the tournament.
"After our dominant display [on Monday] and the win against Portugal, it shows what we’re capable of and I think that’s the aim for us, to go on and win it."
