Earlier this month, Goal revealed that Costa had sealed a £35 million move to Stamford Bridge, after the 25-year-old forward's impressive haul of 36 goals in 50 appearances this season.

"I was going to summon him for the World Cup," Scolari was quoted as saying by O Estado de Sao Paulo.
"Diego Costa would be with us. He could play as a seven, a nine, or even as an 11. I’d thought about playing him up front to run and smash through. He’s a powerful beast. He's strong as a bull.
"Was I wrong? I don't know, but he would be at the World Cup with Brazil. I talked to him twice about it.
"The problem is there were other interests behind it. With Diego Costa becoming a naturalised Spaniard, that opened up his options in Europe. There's a whole set of interests."
Costa has made one appearance for Spain, playing 90 minutes in their 1-0 win over Italy in March, but the striker's World Cup campaign hangs in the balance due to a hamstring injury.
