He has been impressing with his performances and earned rave reviews

Mauricio Pochettino believes there are no limits to what Joshua Onomah can achieve in the game.

The 18-year-old forward was handed his first Spurs start in their Europa League victory against Monaco on Thursday night.

He had already had a smattering of substitute appearances and been training with the first-team for eight months and his transition into his starting debut was seamless. Such was his performance he was unfortunate not to get on the scoresheet.

Spurs manager Mauricio Pochettino has tipped Onomah for success and possibly an England call-up

Harry Kane, Ryan Mason, Dele Alli and Eric Dier have all received England call-ups under Pochettino and the Argentine does not see why Onomah cannot follow them.

Asked if he can go on to play for Roy Hodgson's team, having represented the national team at Under 16 to Under 19 level, Pochettino replied: 'Why not? It is impossible to set the limit for him as he is 18 and is very strong. His quality is amazing and he only needs to work hard and then he'll be fine.

'He is a special boy, a special player, because of his talent, his potential and his body. His body is powerful and he has quality in his feet. I don't know how he will develop.

'Sometimes you get an instinct about a player but I prefer to keep that inside. Football is always about input and feeling and sometimes you don't know why but you think this guy can be a top player.

'Maybe it is about knowledge about football as we have been in football all our life. I think we have a lot of talent here.'

Pochettino is convinced that his methods of subtly integrating academy players with the first team helps them to put in such confidence performances when they are called upon, like Onomah did last week.

He added: 'The problem with the young players is that they play in the U21 and U18 and you pick them one day and it is normal that it is very difficult for them.
