Martin Keown singled out Tottenham defender Davinson Sanchez for criticism after his performance against Middlesbrough on Tuesday night.
Spurs managed to record a 2-1 home victory against Championship opposition Boro in an FA Cup third round replay, which means they will face Southampton in the next stage of the competition.
Giovani Lo Celso scored within two minutes for the North London club after capitalising on a mistake, while fellow Argentine Erik Lamela added a crucial second in the 15th minute.
Despite plenty of chances in front of goal, Jose Mourinho’s team lacked the clinical touch and George Saville’s 83rd minute goal for the visitors set up a nervous finale.
Pundit Keown wasn’t impressed by the display of Sanchez though in the cup and feels he needs to believe in himself.
The 23-year-old centre-back made several individual errors that didn’t go unnoticed and he was perhaps fortunate not to be punished.
“It’s a work in progress for Mourinho. Who’s his best XI? I think Davinson Sanchez, in particular, is suffering tonight,” Keown said on BBC One’s televised coverage (9:34pm, 14 January).
“He’s been in and out of the team but you’ve got to be strong mentally, you’ve got to believe in yourself. When a new manager comes into town, you’ve got to back yourself.”
Sanchez is certainly a highly-rated talent that on his day has proven he can cut it at the top, but on the flip side he can drop some poor displays too.
The Colombian powerhouse has an opportunity to become a regular under Mourinho and he has to start seizing that before he gets frozen out.
He had a few clearances that he struggled to deal with and he needs to become an assured figure at the back.
His passing definitely needs to sharpen up and his latest performance should be a wake up call.
