One of Manchester City's tactics during their Premier League clash with Liverpool caused a disagreement between Sky Sports pundits Gary Neville and Jamie Carragher.
When conceding a free kick within shooting range, City opted to have a player lying down behind the defensive wall in a bid to prevent the ball going underneath the wall as they jumped in the air.
Oleksandr Zinchenko was the man to fill the role for Pep Guardiola's men shortly before half-time in Sunday's showdown at Anfield.
He positioned himself behind the five-man wall - but facing in the opposite direction, towards his own goal.
For some reason, this irked former Manchester United defender Neville, with ex- Liverpool man Carragher saying on commentary: “You don’t like that man, do you, Gary? Behind the wall, facing the wrong way.”
Neville replied: “No, it’s ridiculous. It’s started to materialise a little bit more over the last few weeks.”
Carragher continued: “What don’t you like about it?”
To which Neville responded: “I don’t mind him lying down, it's just why face away?”
Warming to his task, Carragher said: “I think it’s pretty obvious. If the wall jumps...”
The suggestion seemed to be that it would reduce the risk of taking a nasty blow to the face from the free kick.
But an increasingly irate Neville was not having it, hitting back with: “Oh, come on! Should the wall not face away as well then?”
As it turned out, Liverpool midfielder Thiago Alcantara fired the free kick from just outside the penalty area way over the crossbar.
This prompted commentator Martin Tyler to point out, in reference to Zinchenko, that "the draught excluder (was) not needed".
The first half ended goalless after Ilkay Gundogan missed a penalty for City.
Gundogan made up for his error by putting the visitors in front early in the second half.
However, that was cancelled out by another penalty, this time converted for Liverpool by Mohamed Salah.
Gundogan struck again, though, to put City 2-1 ahead entering the closing stages.
