Roberto Firmino believes he improved 'physically, technically and tactically' during his time in Germany, but the new Liverpool forward insists there is plenty more development for him.

The Reds announced today that a deal has been completed, subject to a medical after the Copa America, for the 23-year-old Brazilian to join Brendan Rodgers' squad ahead of the 2015-16 season.

During his four-and-a-half years with Bundesliga side Hoffenheim, Firmino made 151 league and cup appearances and struck an impressive tally of 47 goals.

His form at club level forced recognition on the international stage and the versatile attacker has found the target four times in nine games for his country to date.

Speaking to FIFA.com in March, Firmino said: "When I arrived at Hoffenheim I could already play football, but I've developed physically, technically and tactically since then.

"The Bundesliga is one of the world's best leagues. I had to adapt and improve to get by here, and although I've now reached a good level, there's still more left to do.

"My own dissatisfaction is my biggest motivation."
