Chelsea are expected to announce the signing of Atletico Madrid hitman Diego Costa before the start of the World Cup on June 12. 

John Cross of the Mirror wrote that the deal for the player may be concluded by Friday after Costa resumed full training with the Spanish national side, allowing him to complete his delayed medical for the Blues. 

Cross reported that Chelsea have already agreed wage terms with the player and that Costa is keen to complete his switch to the Premier League before the start of the World Cup.

The deal has been slowed due to Costa's recent injury, which cut short his involvement in the Champions League final for Atletico Madrid.

The west London club will pay in the region of £35 million for the player, per Sami Mokbel of the Mail Online, but they face a battle to hold on to the services of Eden Hazard. Mokbel reported that the Belgian will be the subject of a bid from Paris Saint-Germain. 

Jose Mourinho recently spoke about his team's need for a world-class striker like Costa, per Matt McGeehan of the Mail Online.

The Special One said, speaking to Chelsea TV: 

Against the teams that are more defensive, more aggressive, more worried about trying to keep a clean sheet than really to play, we keep saying the same. We have good players, but we don't have the kind of striker able to, in a short space, to make an action, to score a goal, to open the gate.

In these kind of matches you just need to open the gate. When you open the gate, the gate is open and you go win much more. We weren't able to do that. We have to try to win as a team, to improve as a team, but also add the attacking player with that killer instinct and the number of goals that push teams to different levels.

Costa will be vital to Mourinho's ambitions in winning silverware next season as the club will finally have a striker who can accumulate goals across an entire season. recently highlighted the player's potency in comparison to Zlatan Ibrahimovic, proving just how good he is in front of goal:

Rik Sharma of the Mail Online reported that Mourinho will attempt to bring Costa's current team-mate Filipe Luis to Stamford Bridge, with Atletico Madrid having recently had an offer close to £8 million accepted for Guilherme Siqueira, from Granada. 

Chelsea see the player as Ashley Cole's replacement at left-back, after Luis had a magnificent season for the newly crowned champions of Spain. Sharma writes that the 28-year-old will cost the Blues anything up to £20 million. 

Chelsea are also reportedly in for Pachuca winger Jurgen Damm, per Medio Tiempo (h/t Paulo Freitas of Sky Sports). The 21-year-old has previously been linked with Manchester United, having had a two-week trial with the Red Devils, according to the report.

Both Atletico players would be fine additions to Chelsea's squad but the capture of Costa will be pivotal in Mourinho's rebuilding of the club. Chelsea are a team desperate for firepower in the striker's position and they have never successfully replaced Didier Drogba since the legendary player left the club.

Costa will strike fear into the hearts of opponents next season and he will suit the style of the Premier League. His work in the penalty area will offer the Stamford Bridge club the perfect foil for Hazard and Oscar, and the capturing of an English league title will now be a real possibility.
