Tottenham Hotspur boss Mauricio Pochettino has claimed that Liverpool full-back Trent Alexander-Arnold should have been sent off for a bad foul in the first half of the EFL Cup tie on Tuesday.

The 18-year-old, who made his debut in the 2-1 fourth-round win for the Reds, only received a yellow card for the foul on Ben Davies.

"In the first half the full-back, Arnold, should be sent off for the big tackle, the bad tackle," the Argentine said on Sky Sports.

"It was a little bit strange at the end of the game. The (Liverpool) bench started to complain about us. That was very strange.

"You should stay calm. It is the referee who is the authority to say it was or it wasn't, it was or was not a penalty.

"You need to focus on the game. At the end of the game they started to complain about one action that was a normal foul."
