Chelsea are reportedly planning on making a move for Barcelona star Lionel Messi after the end of this season following reports that the Blues had a €150m (£118m) bid for the Argentine rejected last summer.

Earlier, the Metro had claimed that Barcelona had rejected a whopping bid of over a £100 million for Messi.

It is also believed that the 27-year-old forward, who has scored 359 goals in 432 appearances for Barcelona, is a touch unsettled at the Camp Nou and is seeking a fresh challenge.

Messi may be interested in moving to England as it was earlier reported that the Argentine had asked former teammate Cesc Fabregas about life in the Premier League and Arsenal.

Due to this reason, the Blues are again reportedly planning an audacious bid to bring the Argentine to Stamford Bridge next summer, according to the Metro.

Football agent and journalist Philip Harmeling also claims that the Blues will make another move for Messi, with a similar bid, next summer.

"Few media outlets in Spain reporting that Chelsea will offer €150million to Barcelona for Lionel Messi next summer," Harmeling posted on Twitter.

However, Chelsea will have to bid a lot higher than €150m to convince Barcelona to part with their superstar as the Argentine has a €250m buyout clause in his current contract that expires in 2018.

Last season, approximately around the same time, Manchester City were being linked with a move for Messi, with reports claiming that the Citizens were willing to match the €250m buyout clause in his contract.

However, Messi's father and agent Jorge quashed all the rumours, insisting that Messi loves the club and will never leave Barcelona.

"Leo [Messi] has grown up at Barca and he loves this club. There is no problem at all between Leo and the club's management," Jorge had earlier told Argentinean sports newspaper Ole.

Meanwhile, the four times Ballon d'Or winner says that he "never imagined" that he would score 400 goals (for both club and country) in his career.

The Argentine headed in the landmark goal during Barcelona's 6-0 victory against Granada in the La Liga on Saturday.

And Messi, who has enjoyed a lot a success with Barcelona since making his debut in 2004/05 season, winning 21 trophies, including six La Liga titles and three Champions Leagues crowns, says that he still cannot believe that the has scored as many goals as he has done in his career.

"I never imagined I could achieve anything like this in my career," said Messi on his official Facebook page. "I'll continue working hard to reach more targets."
