Liverpool's refusal to sell Luis Suarez to Arsenal during the summer of 2013 left the player's relationship with agent Pere Guardiola at breaking point, according to the Uruguay international's representative.

Suarez accused the Reds of backing away from a promise to allow him to leave at the end of the 2012/13 season should the club fail to qualify for the Champions League.

The Anfield club then rejected two offers from Arsenal for Suarez, with the second bid of £40m + £1 ($59.8m) reportedly activating the striker's release clause, however it was rejected by Liverpool as the club continued to play hard ball.

The 28-year-old made several attempts to force a move away from Liverpool and public criticism of the Merseyside club saw him train away from the first team squad prior to the start of the new campaign as Arsenal interest continued to be blocked.

Speaking for the first time regarding the pair's strained relationship, Guardiola told FourFourTwo magazine: "This was my most uncomfortable time with Luis. Especially for me and our relationship.

"[It was] because of the confusion, because of what we'd already agreed with the club [to leave in the summer], because situations change and force you to do things that make you uncomfortable.

"It was complicated, and Luis had to train separately from the team. Everything was played out in the press."

Liverpool would later allow Suarez to join Barcelona for £65m in the summer of 2014 after he helped guide the club back into the Champions League with 31 goals last season.

And Guardiola says Suarez followed his heart in moving to the Nou Camp, where he has already netted 20 goals in all competitions.

"Back in Uruguay, Luis had the dream to play for a big European team and he certainly did that at Liverpool, in a league as competitive as the Premier League," he added.

"But Barcelona is always something else; something special. It's a way of culminating, to some extent, his career and journey.

"Speaking honestly, it's the club he loves. The possibility of playing for a club like this comes around very rarely and you have to take advantage of it."
