Mauricio Pochettino believes Eric Dier has transformed into a 'new style' of player.
Dier joined Tottenham from Sporting as a defender. He made his goalscoring debut against Friday night's opponents West Ham alongside Younes Kaboul at centre half but since then has been converted into a holding midfielder.
This season, with the arrival of Victor Wanyama, Dier has balancing the two roles. For Pochettino, Dier's tactical flexibility is bonus.
'It was his first official fixture, he was in the starting XI,' Pochettino said as he cast his mind back to Dier's last-gasp strike at Upton Park.
