Son Hueng-Min says he is excited about Brennan Johnson's talent - but insists it will take a collective effort for Spurs to replace Harry Kane.
Wales forward Johnson, 22, made a deadline day move from Nottingham Forest in a deal worth in excess of £45m.
His signing has been seen as part of Tottenham's efforts to replace the attacking void left in the wake of record goalscorer Kane's move to Bayern Munich.
Son says he is looking forward to lining up with Johnson and seeing him up close when South Korea face Wales in a friendly at Cardiff City Stadium on Thursday.
