Brazil head coach Tite has revealed that his star man Neymar will start the Russia 2018 FIFA World Cup Group E clash with Costa Rica on Friday.

The Paris Saint Germain (PSG) forward has been struggling with a knee problem since the start of the week and was a serious doubt for the game against the CONCACAF representatives.

Tite confirmed Neymar will start during his pre-match press conference earlier on Thursday.

He said: “It’s still the same prognosis. He played his first 90 minutes [against Switzerland] in 3½ months.”

“There is a science [behind the recovery] and calmness.

“Five matches is the minimum he needs; he has already sped up the process. It is on track, don’t worry.” He added.

Neymar was a big doubt for Brazil ahead of the World Cup after he suffered a metatarsal injury in February in the colours of PSG.

He returned to action and was on target in a 3-0 win over Austria on June 10.

Neymar was, however, underwhelming in his team’s World Cup opener against Switzerland, a 1-1 draw.

The result makes the Costa Rica game more important for the five-time world champions.

On the upcoming Costa Rica clash, Tite said: “The game is decisive because of the draw in the first game.”

“We are aware of it. We need a similar defensive performance with greater effectiveness up front.” The Brazilian coach added.

Speaking further, Tite stated that: “The excitement about the World Cup has gone.

The team has greater tranquility, the coach as well, because he is human. I was excited about the first game. Now I am better focused for the [Costa Rica] game. We will make some positional adjustments.” He concluded.
