"But now": Paul Merson is worried £45M Liverpool star will battle in the Premier League

Liverpool signed Luis Diaz from Porto in January earlier this year and the winger has had a flying start to his career on Merseyside.

Diaz, 25, hit the ground running from minute one in a Red shirt, effortlessly slotting into their front three on the left wing.

However, after a great start, the Columbian must be careful as he prepares for his first full season as a Liverpool.

Pundits have claimed that there could an element of 'second-season syndrome' for the player.

"Will find it harder" - Pundit's claim on Diaz

Despite that flying start which saw him bag six goals and five assists in all competitions, Sky Sports pundit Paul Merson believes he will find it harder to make an impact this season.

“Unlike last season, Luis Diaz is on the radar this time around,” the pundit wrote in a Sportskeeda column.

“When he first joined, team talks from opposition managers wouldn’t have really been about him, but now he’s quickly made the left wing his own and will find it harder to make an impact this season.

He also believes that the 'unsung heroes' of this Liverpool side will be required to step up to help get the best out of Diaz.

“They are the unsung heroes of the team and will once again have to be at their best if Liverpool are to compete on all fronts,” Merson said.

If anything, there could be less pressure on the winger with the arrival of Darwin Nunez who is likely to shoulder most of the pressure as the new star signing.
