Former Chelsea striker Diego Costa has vowed to hit the goal trail after sealing his return to the Premier League by joining Wolves.

The West Midlands side have moved for the free agent, 33, after injuries to new signing Sasa Kalajdzic and fellow forward Raul Jimenez.

Costa has been without a club since leaving Brazilian outfit Atletico Mineiro in January and will now look to fill the void up top for Bruno Lage’s men.

On his aims for the season, he said: "Score goals, do the best I can, give it my all. 

"Find my place as a person, a player and understand how I actually feel because this is a big challenge.

"It’s not an easy challenge because you’re not going to play in an easy league and you can’t play it the way you want to. 

"This is a very demanding championship, physically demanding, and it is something to test myself with and I’m ready to give it a go."

The former Spain international returns to England after making 120 appearances for Chelsea between 2014 and 2017, spearheading the Blues to two Premier League titles.

And the Brazil-born striker admitted that the decision to sign a one-year deal was made easier due to the large number of Portuguese players in the squad.

The ex-Atletico Madrid hitman added: "It’s a first-class club with very good players who know how to play football and having the chance to play in the Premier League again was the main thing.

"Obviously, the club influenced my decision, especially knowing I will be able to adapt a lot more easily here not only from a technical point of view, the quality of the players but also from the fact a lot of the players are Portuguese and that will make my transition that much smoother.

"It wasn't in the best terms possible on accounts of a player's injury which, unfortunately, I can only wish him nothing but the best for him.

"But when he [Lage] told me about returning to the Premier League, this is a championship I have related to quite a bit, always liked and followed. 

"No matter how much I enjoyed playing in Madrid, I felt discouraged, but this motivated me. It lit that fire within me."

Wolves are due to host Manchester City on Saturday lunchtime before the international break sees them go two weeks without a game.

That is good news for Costa, who admitted he will need time to get his fitness levels back after nine months without a club.

Costa said: "On a physical and psychological level, I will need two to three weeks to get back in shape. But that’s normal since I haven’t done much for a while — I know that I can do it."
