Mauricio Pochettino praised Armando Broja as one of the most promising young strikers in Europe after his goal helped Chelsea to a 4-0 FA Cup third-round win over Preston.
The 22-year-old started in place of Nicolas Jackson, who is away at the Africa Cup of Nations, and netted his team's opening goal early in the second half at Stamford Bridge.
Preston had done a fine job in the first period of containing Chelsea, who lacked cutting edge to go with their domination of the ball, but Broja's strike was the first of three in an 11-minute spell in the second half.
