Jamie Redknapp hailed Mason Mount’s ‘fabulous finish’ which helped Chelsea to a 1-0 win over Liverpool but singled out Alexander-Arnold for criticism for failing to get tighter on the midfielder for the goal.
The Reds looked set to go into the break with the scoreline goalless after Timo Werner had his goal disallowed by VAR for offside at Anfield.
But Mount had other ideas as he cut inside from the left wing and scored the winning goal past Liverpool goalkeeper Alisson in the 42nd minute.
The goal took the England international’s tally to five goals for the season and Chelsea kept hold of their narrow advantage on Merseyside to climb to fourth in the table.
‘It’s a fabulous finish, of course it is. It’s a brilliant piece of play and once they give you that invitation, you’ve got to take it,’ Redknapp said.
‘But I think when you’ve got the two there against one, you have to do your best to show him down the line.
‘Even if he comes back inside, Trent Alexander-Arnold has got to get there quicker! He’s got to move his feet quicker, he’s got to block the ball.
‘At first I’m thinking show him down the line on his left but once he comes inside, you’ve got to block it. Trent doesn’t do enough for me. I think you’ve got to get there quicker and block it. ‘I don’t want to take anything away from what’s a brilliant goal and they’ve executed that.
And According to Ashley Cole, Alexander-Arnold didn’t help himself in the build-up to the goal by gambling on Mount going down the line.
‘I think the problem with Trent there is that he overcompensated, thinking Mount was going to go down the line,’ the former England left-back said.
‘And then obviously he hasn’t moved his feet quick enough to get out and block it.’
