Having fought tooth and nail throughout his career to earn a move to Barcelona, it was a strange sight when Luis Suarez’s time at Camp Nou came to an end last summer.

So many times before, including at Liverpool, it was the Uruguayan who decided when it was time to leave, often departing clubs in unceremonious circumstances and at a rapid rate.

Suspended for a bite on PSV Eindhoven’s Otman Bakkal at the time of his Ajax departure in January 2011, history repeated itself when the forward finally got his desire move to Catalonia in the summer of 2014, just weeks after sinking his teeth into Giorgio Chiellini at the World Cup.

Had Arsenal been successful in their efforts to lure him from Liverpool the year before, it would have been a similar story following Suarez’s bite on Branislav Ivanovic.

Yet he remains one of the most exciting players Reds fans have ever witnessed in the Premier League era, with his jaw-dropping displays and 31 goals from 33 games in Liverpool’s title near-miss 2013/14 campaign simply out of this world.

In truth, the forward had unfinished business at Anfield when making the move to Barcelona, having failed to deliver a Premier League title.

Such business is now complete, just not by Suarez, with Jurgen Klopp delivering both Champions League and Premier League glory in the past two seasons with his side’s successes ensuring fans no longer pine for the Uruguayan like they once did.

And while bridges were burned slightly by his antics in Liverpool’s Champions League semi-final victory over the Catalans, respect and admiration for one of the club’s most gifted former stars remains along with continued intrigue surrounding their most fascinating enigma.

Afterall, for a player whose career has been shrouded in controversy, it’s impossible to overlook the pure talent that has made him a fan-favourite at every club he calls home.

Except that’s exactly what Barcelona did when deeming the striker surplus to requirements last summer, eventually allowing him to leave for Atletico Madrid on a free transfer.

The narrative pushed last season was one of an out-of-form, overweight player who had become a shadow of his former greatness, now unable to justify his exorbitant wages and enduring a rapid decline.

But, in a surprise to no-one who has ever witnessed the Uruguayan play, Suarez has ensured his doubters have had to eat their words.

With Lionel Messi swiftly announcing his own desire to leave, unimpressed with the treatment of his close-friend, the Catalans have not had to wait long to see the error of their ways.

With the striker boasting 198 goals from 283 games, winning four La Liga titles, the Champions League, four Copa del Reys and both the FIFA Club World Cup and European Super Cup in his six years at Camp Nou, they should have known better.

That included 21 goals from 36 outings in his final so-called washed-up year in Barcelona and the only trophyless campaign from his time in Spain.

Suarez celebrates his 34th birthday on Sunday and he’s showing no signs of slowing down as he looks to ensure his lack of silverware last year was just a one-off.

Boasting 11 goals from just 14 La Liga appearances for Atletico, only Youssef En-Nesyri boasts more while such form has catapulted his new side to the top of the table.

Diego Simeone’s men boast a four-point advantage over Real Madrid and are 10 points clear of Barcelona, and boast games-in-hand on both of Spain’s biggest giants.

Deliver the La Liga title to Atleti and Suarez will effectively achieve what alluded him at Anfield, and at a time when he’s been written off the most since his rollercoaster days on Merseyside.

At a time when Liverpool’s own Premier League title defence is becoming unstuck, compromised by a suddenly muzzled attack, there is an argument that he is the sort of player that the Reds are currently missing who would breath fresh life into their under-threat challenge.

Of course, such an idea is pure fantasy. Suarez’s time at Anfield has long since passed.

But despite Liverpool’s success under Klopp, they are now joined by Barcelona in watching the remainder of the Uruguayan's career with great interest, wistfully wondering what might have been.
