Weaknesses:
Firmino is not yet the finished article, which is understandable given that he is still only 23-years-old, and may not be entering his prime for several more years to come.
Something that will have to be addressed if he was to join the Reds is his physicality as the Premier League has proven many times that it’s a extremely tough competition to get to grips with.
Angel Maria proved last season that talent alone won’t be enough to thrive in England and while it’s not necessarily a weakness it could prevent him from settling down.
