New Atletico Madrid midfielder Matias Kranevitter has revealed that he is ready to play against Rayo Vallecano this week after completing his first training session with the Spanish giants.

The 22-year-old agreed to join Atletico in the summer, but stayed at River Plate to compete in the Club World Cup, before linking up with his new teammates at the start of this month.

The Argentina international completed his first training session on Monday and he has said that he is desperate to play against Rayo in the Copa del Rey this week.

"I am already able to play and I have the confidence of the coach and of my teammates. If I play against Rayo I will give my maximum because it is an important game," Kranevitter told the club's official website.

"I am always eager to play, but I'm under the orders of the coach, and he is the one who decides [who plays]. I am very happy to have joined a club like this – I really wanted to come. This is a unique opportunity that I have to make the most of.

"As the days go by I'll adapt to the game and will bring and willpower. I will try to learn from people with experience in the team. [Diego] Simeone is a winner and has done very well at Atletico. It's a great honour for me that he has signed me. What caught my attention most is how happy and close-knit the group looks. This is why the team is doing well on the pitch."

Kranevitter will wear the No.8 shirt for Atletico this season.
