Atletico Madrid fullback Guilherme Siqueira has hailed the impact of new attacking players Mario Mandzukic and Antoine Griezmann.
Both players are now beginning to find their best form.
"Since Griezmann arrived he has done everything with a great mentality," said Siqueira.
"When he's down, and pulled to the ground, he fights. Mandzukic, the same. One day I say him helping out wide in the full-back position and said 'what are you doing here?' We know what they can provide for us: Griezmann with his talent and verticality, and Mandzukic with his goals."
