If the atletico madrid will buy a great striker (Diego Costa? ) can seriously compete for victory of Liga
No, he is not a great striker. He is just an ordinary player who loving play dirty. But yeah, he is suitable with Atletico's style, which sometimes most of Atletico players played dirty too by making many fouls lol.
That's a skill diego costa have make other player emotional than will get card for as a great finisher maybe yeah by looking when he play for atletico madrid but not when he play for chelsea.
