Dietmar Hamann is not overly concerned by the money Liverpool have splashed on Roberto Firmino.

Liverpool have undoubtedly signed a top quality player in Brazilian ace Firmino but many are concerned as to whether the attacking midfielder will be able to justify his £28million price tag.

However, former Reds star Hamann is a firm believer in Firmino's abilities and has stated that the signing of the Brazil international is probably the best bit of business Liverpool have ever managed to pull off.

Hamann told the Liverpool Echo: "I've not got a problem with the money Liverpool have paid for Firmino.This is a Brazilian international whose best years are well ahead of him, not behind him. He's one of the up and coming stars in Brazil and I think he's worth it.

"Coming to Anfield will be a step up for him but I think he's ready for it. Look at what other clubs are spending. To attract the best you have to pay big money.

"If Liverpool get £50million for Sterling and invest half that money in Firmino the club will have made their best business in a long time – probably the best bit of business since Liverpool managed to sell Jason McAteer to Blackburn for £4million!"
