The 29-year-old winger has scored 23 goals and provided nine assists in 26 matches across all competitions.There have been question marks surrounding the future of Mane, Salah and even Roberto Firmino. The attacking trio have been excellent for the Reds for more than five years now. However, the trio are not getting any younger, with Firmino already 30 and Mane and Salah being 29.There is a reason why some fans are worried by this transfer news. It is worth mentioning that Liverpool have always followed a sell-to-buy policy under the ownership of Fenway Sports Group. However, it is more likely to see either Divock Origi or Takumi Minamino leave Anfield before the January transfer window ends.The Reds had reportedly rejected an initial offer from both AS Monaco and Leeds United for Minamino.Luis Diaz, on the other hand, has had an excellent 2021-22 season thus far for FC Porto. The 25-year-old winger has scored 16 goals and provided six assists in 28 matches across all competitions.Liverpool had made only one signing in the summer of 2021Liverpool were shrewd in the summer transfer window back in 2021 and only signed one player. Ibrahima Konate arrived from RB Leipzig for a fee of £36 million.The Reds spent the majority of last summer offering new contracts to some of their key first-team players. The likes of Trent Alexander-Arnold, Virgil van Dijk, Fabinho and Jordan Henderson all earned new long-term deals in the summer.Liverpool FC@LFC𝗕𝗜𝗚 𝗩𝗜𝗥𝗚 @VirgilvDijk has today signed a new long-term contract with the Reds 2:28 AM · Aug 13, 2021415885109𝗕𝗜𝗚 𝗩𝗜𝗥𝗚 ✊@VirgilvDijk has today signed a new long-term contract with the Reds 🙌As things stand, Liverpool are second in the Premier League standings, having amassed 48 points from 22 matches.
