Marcus Rashford and Harry Kane are reportedly on a list of targets to replace Barcelona star Luis Suarez.
The former Liverpool striker turns 33 in January and his Nou Camp deal runs out in 2021.

Rashford was linked with a move to Barcelona before signing a four-year contract, worth up to £300,000-a-week, with Manchester United in July.
Meanwhile, former United and England defender Rio Ferdinand has urged Kane to leave Tottenham in order to win trophies.

Suarez has won four LaLiga titles and a Champions League trophy since swapping Liverpool for Barcelona in 2014.
Spanish outlet Mundo Deportivo claim Barcelona are also keeping tabs on Paris Saint-Germain and France sensation Kylian Mbappe and Inter Milan forward Lautaro Martinez.
The report adds Barcelona chiefs are ‘more convinced’ by Rashford than Liverpool’s Roberto Firmino, despite his dazzling form for the Reds.

Firmino has netted 19 goals and provided 12 assists since the start of last season.
The Brazilian has helped Liverpool maintain a 100 per cent start to the Premier League this season and an eight-point gap over second-placed Manchester City.round upWSL: Chelsea end Arsenal's unbeaten run, as United, West Ham and Reading all winHonourSporting Lisbon could name stadium after Cristiano Ronaldo, admits club presidentQualityRangers midfielder scores excellent goal against BrazilstatementBalakov: English football has a bigger problem with racism than BulgariaTAKING THE MIP‘Only a matter of time’ - West Ham will sign ex-Man United striker for freeBLOWWales ace Ramsey ruled out of crucial Euro 2020 qualifierupgradeLiverpool want to replace Champions League winner with £20m ace excelling at LeedsOutcastLuka Jovic dropped from Serbia squad as ‘punishment’REVELATION'Of course I'd be interested in a position' - Man United legend open to returnHEROItaly star refuses to leave children's hospital having beaten cancer twice himself
In stark contrast, Rashford has failed to score from open play since the opening day of the campaign with United just two points above the relegation.

And while Kane has already netted seven times this term, Tottenham have managed only three wins from their opening 11 matches in all competitions.
Rashford or Kane would have big shoes to fill in the shape of Suarez, who has scored 135 goals in 169 LaLiga games.
