Arsenal have lost a lot of players to Barca in the past and won’t want to be in that position again. Cesc Fabregas left in his prime in 2011, four years after club-record goalscorer Thierry Henry moved to the Nou Camp.
Those aren’t the only two to have made the move from Arsenal to Barca. Alexander Hleb (2008), Alex Song (2012) and Thomas Vermaelen (2014) followed the same path, and going either further back, both Emmanuel Petit and Marc Overmars did the same in 2000, with Sylvinho joining a year later and Giovanni van Bronckhorst in 2004.
The most recent examples are Pierre-Emerick Aubameyang in January and Hector Bellerin on deadline day this summer. But perhaps the departure of Patino would be the hardest felt in the long run, with the starlet having only turned 19 last month.
