There is too much positivity in this thread. I think we need some balance but Fordy is not available, so here is some balance.
1. He is overpriced. People were saying Lallana was overpriced but Firmino's stats are not significantly better and he will cost more.
2. Another player from a midtable club. Okay its a German midtable club and he is Brazilian but if his name was Rob Firm and he was from Stoke I doubt many here would be excited. For all we know he is another Stewart downing.
3. He doesn't have any experience playing in European competitions or at a top club.
4. He was wanted by Liverpool's scouting team, so its safe to assume he is no good.
5. He is not ambitious enough. If he wanted to win trophies, he would have gone to a club like City or Chelsea but he is coming to Liverpool. Why can't be ambitious like Sterling?
6. If he is any good, he will be playing in Madrid in 2 seasons.
