Heung-min Son admits his difficult start to life at Tottenham left him desperate to return to Germany, before Mauricio Pochettino persuaded him to stay.
The South Korea international became the most expensive Asian player of all time when he joined Spurs for £22million from Bayer Leverkusen in 2015.
However, he initially struggled to justify his price tag amid problems with the pace of the Premier League.
“The Premier League is different,” Son told Goal.
“I do not want to compare this with the Bundesliga, because the Bundesliga has great quality, but in the Premier League everything goes faster and is much more physical.
“At the beginning I played and also scored some goals. Unfortunately, I injured myself and it was difficult to find a connection to the team again.

“I did not get any more games and wanted to go back to Germany because I felt very comfortable there.
“But the coach has always encouraged me. He was the right coach for me in this situation.
“I said I’d like to leave the club, but he really wanted me to do well at Tottenham. He gave me new self-confidence.
“The talks went so well that at some point I pushed aside my thoughts of change.”
