He didn't have the same work rate early on, although that might have been less his fault and more how he had been utilized before then. After six months of so he seemed to be a different animal, more effort he became the bobby we know and love today. He really evolved quickly after joining us.
as I recall it was almost all he had as he was played right wing in a poor team where he could have little impact but to work hard. he didn't have the pace to play rw. Rodgers deserved the sack really for that alone. he never wanted firmino did he? as I recall there was a compromise to get him if Rodgers got benteke
