Wilder vows to protect Blades' interests amid criticism from Liverpool's Klopp

Klopp has repeatedly called on the Premier League to rethink its decision to stick with a maximum of three substitutes per game, and criticised broadcasters over hectic match scheduling that he thinks is leading to more player injuries.

The Liverpool boss stepped up his criticism after Saturday’s 1-1 draw with Brighton & Hove Albion and took aim at Wilder, who had been critical of Klopp and other big club managers for demanding five substitutes be allowed again in the league.

The Blades are among the few clubs who have opposed five substitutes out of concern it benefits teams with bigger squads.
