Former Everton midfielder Leon Osman has showered praise on Allan, suggesting other Premier League clubs have missed a trick by not signing him.
Allan was one of the midfielders who were available in the market during the summer transfer window. Carlo Ancelotti returned to his former club and secured his signature, paying a handsome £21.7m fee to Napoli.
The Brazilian defensive midfielder has quickly settled in at his new club and has formed an excellent partnership alongside another summer signing Abdoulaye Doucoure.
Osman has claimed that of all the summer signings made by the club, Allan has impressed him the most.
