Liverpool throw-in coach Thomas Gronnemark has hit back at club legend Steve Nicol over criticism of his role.

His position has often been scrutinised with former Liverpool defender Nicol again expressing his doubts earlier this week.

But Gronnemark took to social media to hit back and suggested Nicol's criticism is unjustified.

"Two kinds of criticism. The constructive - where people are suggesting potential improvement based on knowledge, and make people or projects grow.

"The destructive - where people are criticizing from an uninformed position, or do it because of self promotion. What do you choose?"

The stats back up Klopp's decision to draft in specialist Gronnemark, who is making an impact at Anfield.

Liverpool have been shown to have a ball retention on throw-ins of 68 percent, compared to 48 percent for the rest of the Premier League.
