This summer promises to be a significant one for Atlético Madrid. The capital club sit second in La Liga, with a comfortable gap above age old rivals Real Madrid, but it's been an underwhelming season overall.
Atlético failed to ever truly threaten Barcelona's position as league leaders, and exited the Copa del Rey to Girona in the last 16. The Champions League provided the biggest dose of disappointment, though, as Atlético squandered a 2-0 first leg advantage against Juventus and crashed out courtesy of a hat-trick from old foe Cristiano Ronaldo.
It's more than just disappointing results that will be causing Diego Simeone a headache this summer, with the Argentine set to lose a number of key players.
