Charlie Taylor is being monitored by Liverpool ahead of the summer transfer window, Football Insider sources understand.

The Leeds left-back has emerged as one of the outstanding players in his position in the Championship on the back of a second consecutive impressive campaign.

Taylor, 22, is about to enter the final year of his contract at Leeds and the Yorkshire giants could be ready to cash in on him this summer rather than lose him for nothing in 12 months.

A well-placed Liverpool source has told Football Insider that Taylor has been added to the club’s left-back shortlist as they eye a new player on the left side of defence to compete with first choice Alberto Moreno.

The Merseysiders are also monitoring Celtic’s Kieran Tierney, Leicester’s Ben Chilwell, Lorient’s Raphael Guerreiro, PSV Eindhoven’s Jetro Willems and Cologne’s Jonas Hector.

However, Celtic revealed earlier in the week they are planning to extend Tierney’s deal until 2021 and hand him a significant pay rise.

Chief executive Peter Lawwell is hopeful the new contract for the teenager can be secured within weeks to fend off interest from suitors including Liverpool.

“Kieran has three years left after the summer,” Lawwell told the Scottish Sun. “He’s done brilliantly well and normally when that happens we’ll sit down with them and try to reward them.

“We’ll do that with Kieran and look to extend his contract. I’m sure that’ll happen over the summer.

“The kid wants to stay and we’re eager for him to stay.”

Taylor has been a mainstay of the Leeds team since establishing himself as a first-team regular following his graduation from the club’s academy.

In other Leeds news, a 35-year-old has emerged as the new odds-on favourite to be the club’s next manager.
