Eric Dier has been touted as one of England's best young defenders in some time.
Eric Dier's signing is one that proves there is no strict formula to what does and does not work with players. In this case, it is seen in Tottenham's use of young, well-regarded English defenders.
Steven Caulker was rated by many Spurs fans as someone who could become a regular in the club's defence for years to come. Instead, he was moved on to Cardiff City last year and has since joined Queens Park Rangers.
The arrival of Dier, 20, has partly led to the departure of the similarly versatile Fryers to Crystal Palace. While Fryers had and now Dier is getting first-team opportunities, 22-year-old Grant Hall is spending another season away on loan (this year with Birmingham City).
Hall is an unknown when it comes to top-flight football. Based on what we have seen so far, however, Dier seems like he might have the aptitude to make it with Spurs in the Premier League.
Used at both right-back and centre-back already this season, where he might excel long-term will only become apparent with time, though Pochettino made sure to mention his versatility in his reflections on Spurs' summer signings.
Dier still has work to do learning the tricks of the trade that will stand him in good stead (such as not pulling the shirt of one of Liverpool's many contact-phobic players in the penalty area, as seen in the penalty he gave away last Sunday). Already, however, he has shown good timing in the tackle, decent positional sense and a helpful burst of speed.
Of Spurs' centre-back options heading into this season, only Vlad Chiriches was under 25. Age was not a pressing concern in the position, but getting an idea of what Spurs' future there might look like now in the form of Dier was not a bad idea.
