Tottenham Hotspur manager Mauricio Pochettino says the club must be certain of identifying the "right profile" of striker if they are to add to their artillery in the January transfer window. Pressure on the Spurs boss to improve his attacking options eased as goals from Heung-min Son and Nacer Chadli downed Leicester City in the FA Cup third round replay, with leading scorer Harry Kane only required for a brief cameo at the King Power Stadium.

Kane played the final 30 minutes against the joint Premier League leaders who were unable to cope without their leading marksmen Jamie Vardy – who was a second-half substitute – and Riyad Mahrez. Son struck in the first half with a bullet shot that flew past Kasper Schmeichel, before the South Korean played through Chadli in the second half to confirm the win.

Despite the heroics of Son and Chadli, the onus remains on Kane to produce the goals that will inspire Tottenham on three fronts this season. Pochettino's side currently occupy the fourth Champions League qualification place and are just five points off Leicester and Arsenal in the table, but there is little support for Kane, who has netted 15 goals in all competitions this term.

"Games like today [Wednesday 20 January] show me we are in the right way," the Spurs boss responded to questions regarding whether a striker would arrive this month, according to the Daily Telegraph. "We have one of the best strikers in the world [Kane] and if we add another offensive player we have to have the right profile because if you buy the wrong player then you break the balance of the dressing room.

"I can understand that when you don't score, people can be worried, but we have enough quality. Today was a good opportunity for Nacer and Son to show that they can score so we are very pleased. [Tottenham] can improve, yes, and if we find the right player, then OK, but if not, I am very happy with the squad that we have. We have a strong squad, and that is my real thought."
