Tottenham Hotspur forward Son Heung-min put in another disappointing display during the FA Cup win over Portsmouth.

The Lowdown: FA Cup victory

Spurs kicked off their FA Cup journey as an improved second-half performance was enough to see them over the line against their League One opponents in the third round.

The tie was decided by a Harry Kane classic as he whipped home a strike from the edge of the 18-yard box in typically unerring fashion.

Spurs certainly didn’t pick up from where they left off following a rampant second-half display at Crystal Palace in the 4-0 win just days before, but nonetheless, the Premier League side got the job done.

The Latest: Son’s performance panned

Despite bagging in the win over Palace to break his domestic duck, having last scored in September, Son’s chase to grab more goals and get on a good run of form was wasted against Pompey.

London World's Rahman Osman gave the player ratings from the FA Cup clash and expressed his dismay in his review of the South Korean, handing him a 5/10 rating.

He wrote: “Still not just himself in a season that has been so frustrating for one of Tottenham’s best players.

The Verdict: Struggling season

Son has been miles off the level he was at last season when he bagged joint-top goalscorer with Mohamed Salah.

The Eagles clash marked only the third game in 23 that he’d scored in all season, showing just how significant of a drop-off he’s had this campaign.

According to Sofascore, the South Korean failed to complete any of his three attempted dribbles, alongside only five out of 13 successful crosses, with his wastefulness summed up in losing possession 20 times - the second-highest of any Spurs player.

Therefore, Osman's low rating for Son appears to be more than fair.
