Liverpool throw-in coach Thomas Gronnemark has slammed Arsene Wenger's plans to introduce kick-ins to football.

On Monday it was announced that football's lawmakers IFAB have agreed to test kick-ins as a replacement for throw-ins to speed up the game. FIFA president Gianni Infantino said proposals were in place to test kick-ins, first suggested in a raft of potential reforms put forward by Wenger in 2020.

"It would be the biggest mistake," Gronnemark told Sky Sports.

"They would be taking a beautiful thing away. But I am 100 per cent sure they will keep them because they will soon see if they trial it that maybe the ball won't be lost as much with no pressure on the kicker and it will ruin the joy of the game for everyone."

Elaborating as to why it would be ruinous for football, Gronnemark believes it would just mean more long balls will be played as teams go direct and try to pack the penalty area.

"There are many different reasons for it,' he said when explaining his reasoning.

"First of all, one of the big challenges with kick-ins is that when you have a free-kick in the opposition half there are teams who decide to put a lot of people into the box and treat it like a corner but from further out.

"Introducing kick-ins will, for sure, bring more long balls into the game. There is no doubt about that. But even though that is a big challenge, and one of the big differences to a throw-in, for me it is just the start of the challenges that come with kick-ins."
