Has Son signing already proved a masterstroke in a very unexpected way?

The Tottenham Hotspur recruit has already shaken things up at White Hart Lane, judging by the form of his team-mates.

There was plenty of attention surrounding Heung-Min Son's Tottenham debut on Sunday afternoon.

The 23-year-old lasted the majority of the north London side's 1-0 win at Sunderland, even though his involvement coincided with a very uninspiring Tottenham display.

As for Son's performance itself, it wasn't bad by any means. There was an evident lack of decisiveness and end product but nothing that suggested he won't start firing in the capital soon enough. The South Korean was rough around the edges but showed plenty of the requisite signs for success.

And yet his biggest impact seemed to be the effect he had on his rivals for a place out wide for Spurs.

Indeed, Erik Lamela and Andros Townsend's game-changing performances at the Stadium of Light have by now been well documented.

They may return to their natural state of hibernation soon but the immediate effects of Son's Tottenham move appear to have been motivational for the Argentina and England internationals.

Lamela created four chances in just 23 minutes, assisting Ryan Mason's winner, while Townsend beat his man continually without cutting inside and... well, Spurs fans need no description of what the usually wasteful winger is normally like.

Against Sunderland, though, there was a definite spark. It appears Lamela and Townsend have both got the message. The Tottenham hierarchy and manager clearly weren't happy with their wingers - why else would they bring in Son and Clinton Njie?

But the duo have responded well. Could the Son signing already be proving a masterstroke - just in a way most wouldn't have expected?
