However, Firmino is in a different league to Deulofeu. It is like comparing supermarket own brand baked beans with Heinz baked beans. While one player has been one of the stars of the Bundeliga for a couple of years and broken through into the Brazil team, the other has struggled for game time or consistency at all clubs he's been at. Deulofeu, up to date, has not shown he is at a consistent premier league standard yet never mind top 4 standard.
Hardly a fair comparison, one is a 2nd striker, the other is a right winger, one is 23, the other is 21.
How has Firmino shown he is PL standard or top 4 standard? Baseless arguement.
How has Deulofeu struggled for game time? he played 28 games for Sevilla last season. Scoring 3 goals and getting 10 assists. The season before he scored 4 and got 5 assists in 29 games for Everton from the wing.
At the same age, Firmino wasn't as good as Deulofeu is now.
Deulofeu is getting better with age and at 4.2 mil, he is a steal.
