The young Irish striker is continuing to develop but will likely need to head away from Tottenham for another season to do so

New Spurs head coach
Nuno Espirito Santo does occasionally switch to playing with two up front but mostly prefers a lone front man with wingers either side.
Last season brought two very tough but educational loan moves for him as he began the campaign at Millwall in the Championship and then dropped down to League One in January to play for Ipswich.
The young Irishman got plenty of game time under his belt, playing as a support striker, out wide on occasions or up front alone on others.
For someone so prolific in front of goal in youth matches, both loans were an eye-opener for the teenager as to just how much he will have to adapt to and learn the senior game.
While he clearly has the skill and a growing physicality to his game, there is more to that in being a goal scorer at senior level with the nous that brings the required movement.
He was unable to score for Millwall in his 13 appearances across London, while he scored twice at the level below in 18 games for Ipswich.
Parrott did end the season with a landmark though as he netted his first senior goals for the Republic of Ireland, scoring twice to turn around a friendly against Andorra.
It is just the start of Parrott's journey into senior football, having made his debut for Tottenham the previous season in the Premier League, FA Cup and Carabao Cup.
While he was the interim head coach at Tottenham, Mason was asked about Parrott's development.
"
Troy has gone out on loan this season and he's been exposed to something he's never been exposed to," he explained.
"The club obviously believes in him, we believe in him. He's obviously had some difficult moments but that's absolutely normal. That's normal."
Parrott was gifted with plenty of natural talent and that's why Tottenham fought off competition from plenty of other Premier League clubs to bring him over from Dublin-based youth team Belvedere.
Espirito Santo worked with 18-year-old striker Fabio Silva at Wolves last season, who as one of Portugal's most talented teenagers still found the English game a whole new experience, and the new Spurs boss will want to take a closer look at Parrott before any final decision is made about the Irishman.
