Manchester United legend Rio Ferdinand believes Liverpool should have sold Roberto Firmino instead of Sadio Mane before the start of the season.The Senegal international joined Bayern Munich last summer for a fee of £32.5 million including add-ons. He had entered the final year of his contract at Anfield after last season.As per the Daily Mail, the former Southampton winger is earning £250,000 a week in wages at the Allianz Arena. Mohamed Salah, meanwhile, was handed a new three-year contract last summer, which put him on a club-record salary of £400,000 per week.Ferdinand has been left baffled by why the Reds didn't budge into any apparent wage demands Mane may have had. According to him, selling Firmino, who also entered the final year of his Liverpool deal at the start of the season, would have been wiser.GOAL@goalWhat a year for Sadio Mane 765333322What a year for Sadio Mane 🏆 https://t.co/0x6NQWEz8DHe said on his YouTube channel (h/t Liverpool.com):"Why didn't they just pay him the money to stay. I think they let the wrong one go. They should have let Firmino go."I just don't understand how you let someone who is actually world-class at that moment in time, who ideally would have liked to have stayed if you gave the contract he was looking for, or something similar to what Salah got."I just can’t get my head around it. Every Liverpool fan must be sat there thinking, 'Wow, how have we let this slip through our hands, a player of that caliber?"Mane, 30, was arguably the first major signing of manager Jurgen Klopp's reign in Merseyside. He registered 120 goals and 48 assists in 269 games across competitions during his six seasons with the Reds.His 23 goals and five assists in 53 games across competitions last term pushed the Premier League giants towards an unprecedented quadruple. While they won just two of four possible trophies, Mane also helped Senegal win their first-ever AFCON trophy last year.Tunde Asiwaju@TundeAsiwaju1FC Bayern Munich has an amazing attacking trio 2022/23 (all competitions) Sadio Mane 23 games, 11 goals & 4 assists Jamal Musiala 22 games, 12 goals & 10 assists Serge Gnabry 23 games, 10 goals & 10 assistsFC Bayern Munich has an amazing attacking trio 2022/23 (all competitions) 👏🇸🇳 Sadio Mane ▪️ 23 games, 11 goals & 4 assists 🇩🇪 Jamal Musiala▪️ 22 games, 12 goals & 10 assists 🇩🇪 Serge Gnabry ▪️ 23 games, 10 goals & 10 assists https://t.co/V7eLqfdFl2Agent gives update on Firmino's contract talks with LiverpoolLiverpool are eager to hand Roberto Firmino a new contract before he becomes a free agent this summer.
