Danny Mills urged Troy Parrott to go out on loan next season in order to get the vital experience needed to succeed at Tottenham.
The former Leeds United full-back, speaking exclusively to Football Insider, claims it is about learning that your “decisions have far greater consequences” in first-team football.
The 18-year-old has been in scintillating form for the Spurs youth sides – scoring 11 goals in 7 appearances this season.
However, Parrott has featured just four times for the first team this campaign – each as a substitute.
This is despite Harry Kane and Son Heung-min being sidelined through injury since New Year’s Day and mid-February, respectively.
When asked by Football Insider if the young striker should consider a loan move ahead of next year, Mills said: “He is getting excellent development at a massive club but once you have got beyond that and you are good enough to be in the first-team somewhere there is no substitute for playing football. He needs to be brave and accept it is not going to happen this season.
“Harry Kane did it, Tammy Abraham has done it. David Beckham and John Terry did it.
“You can only learn so much in training. It is about having to make decisions that matter. Decisions do not matter at under-23 level. They don’t cost people their jobs, three points, win bonuses, or relegation.
“It is going from a child’s world into an adult world. Suddenly your decisions have far greater consequences.”
The club confirmed in February that the teenager had signed a new deal with the Lilywhites until 2023.
Tammy Abraham is the latest English striker to see a loan move pay dividends. The 22-year-old has established himself as a first-team regular at Chelsea following loan spells at Aston Villa and Swansea.
