Heung-min Son is questioning his long-term future at Tottenham, according to the London Evening Standard.
Tottenham shelled out £22m to sign Son from Bayer Leverkusen in 2015 but the 24-year-old has struggled to make an impact since.
The South Korea international was linked with a return to Germany during the summer but instead decided to work even harder to force his way into Mauricio Pochettino’s first team plans.
However, Son has reportedly become disillusioned with life at Spurs and doesn’t feel he has the full trust of Pochettino.
In 90 minutes of Premier League action this season Son is already half way to matching his tally for goals in 28 appearances last season (4 goals).
