If there was one unexpected hero during Liverpool's romp to the Premier League title, it was Luis Diaz.

Not that anybody wasn't anticipating the Colombia winger having a major say in the Reds' record-equalling 20th championship triumph.

Instead, eyebrows were raised in how his impact was achieved, Diaz starting a third of the top-flight campaign playing as the central striker rather than on his more accustomed left flank.

But with two years remaining on his current contract, a difficult decision awaits Liverpool.

At the age of 28, Liverpool have a player who is, theoretically, at his peak in Luis Diaz.

And having come off his most productive season to date with the Reds with 17 goals and 13 in the Premier League for the champions, those statistics very much prove that aforementioned theory.

Increasingly, though, for those tasked with governance of the top clubs, one eye is kept on the future and with two years left on his current deal, there is a decision to be had at Liverpool over Diaz.

Had the Colombian been 26, it would have been a no-brainer to offer an improved deal given his contribution to the team and versatility across the front line.

And were Diaz in his thirties, the Reds would have qualms keeping him until the end of his deal and then allowing him to depart on a free transfer, similar to the exits of Gini Wijnaldum and Roberto Firmino.

Instead, the forward is somewhat in between, already in his expected peak years but most likely, if normal trends are considered, to be slightly beyond that at the end of any contract extension.

It means any team making an offer now would probably have to spend a decent whack to prise him away from Anfield in the knowledge he almost certainly has another good three years left in him

Otherwise, there should be no great desire to part ways with Diaz and weaken Arne Slot's attacking arsenal.

Both Liverpool and Luis Diaz will have a pretty big decision to make this summer.

With Diaz recently turning 28 and with talk of interest from Barcelona and Al Nassr showing no signs of slowing down, it seems almost certain that the Colombian will be penning fresh terms before the transfer window closes on September 1.

But whether those improved terms are signed at Anfield, where he currently has two years left to run on his current deal, or elsewhere remains to be seen.

Of course, after Diaz played a starring role in the Reds' Premier League triumph - returning 13 goals and seven assists - it would be foolish for Liverpool to actively try and offload the No.7.

But if one of the four Saudi Pro League clubs backed by the Public Investment Fund were to table an eye-watering bid for the forward, even at half of what Al Hilal are willing to pay for Manchester United captain Bruno Fernandes, Liverpool would be wise to cash in.

On the other hand, Diaz would surely only stay at Anfield if he is offered a new contract
