The BT Sport pundits are huge admirers of the brilliant Brazilian, who will cross swords with Barcelona again on Thursday, after receiving a hot reception at the Nou Camp due to his Real Madrid past.
Scholes believes the summer signing is the closest thing to his former team-mate Roy Keane we have seen, while Hargreaves pinpointed one key area of the 30-year-old's game that would have made him a dream player for Sir Alex Ferguson.
For all the plaudits the midfielder has received this term, he is still not appreciated enough in the eyes of the two former Reds.
