Tottenham Hotspur crashed out of the FA Cup to lower league opposition and it was another game in which Heung-min Son flattered to deceive.

In a game of very few chances, it was Championship outfit Middlesbrough that ran out victors at the Riverside Stadium on Tuesday night, thanks to a goal from teenage substitute Josh Cobern, who netted an extra-time winner to remove Spurs' final hope of silverware in 2021/22.

"When you play this type of game, you have to be very good from the start," manager Antonio Conte said after the defeat. "We had the chances to score and to kill the game but we didn't take them."

The South Korean attacker was one of those wasteful players as he failed to find the net from four shots on target. His tally alone accounted for 66.6% of the Lilywhites' total efforts on target, so it's no wonder they never found the net across 120 minutes.

You'd have expected Son to deliver based on his performance against Leeds United at the weekend but that may have proved to be an anomaly in a tough run of form for the 29-year-old as he went missing up at Burnley, a result that left Conte questioning his future at the club.

He had zero shots on target that day, so this time, he was just more lacklustre with his attempts, having been given a chance to change the game. Again, though, he let his manager and the side down.

Elsewhere, he proved to be one of the most ineffective players on the ball, failing to register a single successful dribble from three attempts. A poor return up against a Championship backline and considering his top-flight average of 1.7 successful attempts per game.

He also lost possession 24 times, more than anyone else on the pitch, effectively handing the ball back to the opposition all game, so not only was he fruitless in front of goal but he was also careless and quite the liability.

Son was weak in his battles, too, having won only four duels from 13 attempts (30.7%).

It was a display that Press Association journalist Jonathan Veal described as "shocking", whilst football.london reporter Rob Guest claimed he had "a wretched evening" up at the Riverside.

Plenty of stars took the flak on social media, including Pierre-Emile Hojbjerg and Ben Davies, but none were as wasteful, ineffective and weak as Son, who once again failed the Italian head coach in what has been a lacklustre run of form lately.
