And former Arsenal man Merson is expecting Liverpool to be one of the Premier League’s busiest clubs during the summer transfer window after a quiet January on Merseyside.
Asked to rate Liverpool’s January transfer dealings, Merson told Sky Sports: “Their business will be done in the summer.
“I think Jurgen Klopp’s come in and thought ‘let’s get this season out of the way now’ and will be thinking ‘this is a lot harder than I thought it would be’.
“I think they’ll do more business than anybody in the summer and there’ll be more ins and outs at Liverpool than at any other club.
“I think he’s just waiting for next season. You can’t really give them a mark because they haven’t done anything, so it’s just a D.”
Liverpool are preparing for their trip to Leicester City in the Premier League on Tuesday night after their goalless draw against West Ham in the FA Cup at the weekend.
