Tottenham Hotspur captain Son Heung-min bemoaned his team's lack of concentration in their 2-1 home loss to Leicester City on Sunday and said they are trying to block out the noise amid a woeful run of form. Leicester came from a goal down to beat Spurs and heap more pressure on the North London side's manager Ange Postecoglou, who has been dealing with a lengthy injury list that includes goalkeeper Guglielmo Vicario, centre backs Cristian Romero and Micky van de Ven and striker Dominic Solanke.
