Tottenham's Jan Vertonghen in action with Anderlecht's Yoeri Tielemans
Spurs were linked with a move for Tielemans last week and with his club failing to provide European football he may well be considering his options.
The 19-year old is one of the most sought after young players in European football and the Lilywhites would face massive competition if they were to target him.
Yet Spurs now have Champions League football to offer and they have proven themselves to be a prime destination for young talent.
Tottenham manager Mauricio Pochettino
Mauricio Pochettino’s rein has been characterised by the promotion of youth, with the likes of Harry Kane, Dele Alli and Eric Dier all flourishing under his watch.
It’s that commitment to giving youth a chance which helped secure the signing of promising striker Vincent Janssen ahead of PSG, as reported by the Mirror, and Spurs are now one of the most attractive options for young talents wishing to progress.

The signings of Janssen and Victor Wanyama addressed the two major issues in the Spurs squad but the matter of who provides cover and competition for Mousa Dembele has yet to be determined.
Tielemans is the ideal candidate to complement his compatriot and Daniel Levy should be doing all he can to make a deal happen.
