Manchester City and Chelsea are hoarding England's top youngsters with no intention of playing them, Sir Trevor Booking has said.

The England legend has slammed the Premier League's mega-rich clubs for not giving the likes of Patrick Roberts and Ruben Loftus-Cheek enough first-team opportunities and stunting their growth.

The former FA head of youth development also said the Premier League rules regarding home-grown players need to be rethought if England's exciting crop of youngsters are to have a chance of winning Euro 2020.

Brooking believes the 18-year-old midfielder has the potential to be a top player for the England senior team

Roberts, signed by City from Fulham for £8million in the summer, is just one example of the trend according to Brooking.

The 18-year-old midfielder has only played four minutes in the Premier League since arriving at the Etihad and now looks set to be sent out on loan.

'Patrick has the potential to be a special player and an England regular,' Brooking told the The Sun.

'He's part of very talented crop of youngsters we have who could win Euro 2020. But he needs to play in order to develop – and that is not happening.'

Ruben Loftus-Cheek scored for Chelsea in the FA Cup but has still not completed 90 minutes for the Blues

Loftus-Cheek has appeared at four different levels for England including Under 21 and turns 20 this week

The former West Ham midfielder also took aim at Chelsea, who despite their poor season and a number of under-performing players, have not given the likes of Ruben Loftus-Cheek and Jake Clarke-Salter a real chance in the first team.

England Under 21 international Loftus-Cheek turns 20 this week, but has not completed 90 minutes for the Blues despite making his debut in December 2014.

'I thought Loftus-Cheek had a chance this season because Chelsea's midfielders have struggled but he hasn't had a look in,' said Brooking. 'He's tall, athletic and good on the ball.

'Clarke-Salter can form a brilliant centre-half partnership with John Stones for England. Players need the opportunity to develop through.'

Part of the problem according to 67-year-old is the Premier League rule that states clubs must have at least eight home-grown players in their 25-man squads.

However, as players under the age of 21 count towards the quota but do not take up an allotted place, the richest clubs are buying the top young players to warm their benches.
