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.
Diego Costa is perfect for the style of play of D. Simeone . With Griezmann form a pair of at least 50 goals at season . Imagine Diego Costa in place of F.Torres that is no longer that of 10 years ago.
I am convinced that with Diego Costa or another striker at this level ( for example Lacazette ) the atletico madrid will win la liga .
