Benfica boss Bruno Lage has already described Silva as a 'fabulous player' and a 'symbol' of the club. They will, however, have to sell a major player this summer before they can make a heavy investment in the transfer market. Silva's arrival could also mean that Angel Di Maria may leave the club. A final decision is yet to be taken on the Argentine's future, and president Rui Costa is expected to speak to the World Cup winner at the end of the season.
