However, Murphy also added that Emile-Smith Rowe is not guilty of the same thing by signing a new long-term deal with rivals Arsenal this summer.
Son is now 29-years-old and his new contract, running until 2025, would take him up to the age of 34.
The South Korean forward has been a key asset to Tottenham since joining from Bayer Leverkusen in 2015, scoring 107 goals and grabbing 64 assists in all competitions.
Last season was the 29-year-old;s most prolific, scoring 22 goals and providing 17 assists in all competitions and his partnership with Kane was not only a bright spot in a dim season but a record-breaking one.
Kane and Son combined for 14 goals in a single campaign, which is more than any other duo in Premier League history after they overtook Alan Shearer and Chris Sutton who managed 13 for Blackburn Rovers during the 1994/1995 campaign.
Murphy, however, stated that Son is showing a lack of ambition by signing a new deal.
He said: “Son is 29, so he is in a much more content frame of mind where he knows what he likes, where he is, and how he enjoys his environment.
“Financially, he is fine and he is in last chance saloon, which is why I said what said that it is a little bit stranger because he is nearing the end and it’s highly unlikely he is going to win silverware at Tottenham in the next few years.
The ex-Premier League footballer compared to the situation to Smith-Rowe but stated they are very different by suggesting Arsenal are a ‘bigger club’.
“Emile Smith Rowe, on the other hand, has wonderful talent a big fan of his. It’s not relevant when you are that age. He’s also at a bigger club, more successful in the last decade and 20 years. It’s trying to get back.”
Harsh, and didn’t expect it from an ex-Spurs man. I think a lot were surprised when Son did indeed sign a new deal of that length.
But it’s a testament to Son’s character and genuine love for the club that he wants to try and win trophies for this club and it feels harsh to pop a dig at him, and Spurs, for that.
