#4 The departure of Paulinho
Another player whose arrival was surprising owing to the difference in his style of play and that obtainable at Barcelona.
After showing much promise in Brazil with the national team and his club Corinthians, Paulinho made the move to Tottenham in 2013 where he generally struggled to live up to expectations before going on to China after just two seasons at White Hart Lane.
In the Chinese Super League, he rediscovered a bit of form, but it was still very surprising to see Barcelona shell out €40 m to purchase him, and after much scepticism over the transfer, Paulinho was able to redeem himself with some solid displays, scoring 9 goals in 49 matches to help the Blaugrana to a domestic double.
Despite receiving praise, Paulinho failed to fully win the critics over with his performance, and his current loan spell back to China after just a season shows that his display at Barcelona was plain and effective rather than exceptional.
Arturo Vidal's signing from Bayern came less than a month after the departure of Paulinho, and it begs the question as to why Barcelona spent such an amount of money to get a player with a similar skillset and playing pattern and who is also a year older than the Brazilian.
