Considering that Atletico Madrid, which is playing in the third line in two or two months, will play 14 games in a row, in order to further increase the depth of the team's bench, the club also brought in Diego R, the midfield core of the Bundesliga club Wolfsburg, at a low price of 1.5 million euros on the eve of the winter transfer window.

In fact, if it weren't for the fact that Brazilian star Diego's contract with Wolfsburg would expire this summer, Atletico Madrid would not have picked up this big bargain.

Meanwhile, Chelsea FC, who had temporarily abandoned their intention to bring in Diego Costa due to injury, have rekindled their interest in his performances in recent times and have made a €60 million offer to Atletico Madrid just before the winter transfer window closes.

As Chelsea FC's offer of €60 million is already in excess of the "€50 million in liquidated damages for foreign clubs" stipulated in Diego Costa's new contract, Atletico Madrid will face the harsh reality of losing a key point of attack in the winter transfer window as long as Diego Costa and Chelsea agree on a personal salary.

However, to the surprise of the club's general manager, Paolo Forley, Mendes, who had been hoping to earn a large commission through the transfer of Diego Costa, politely rejected Chelsea's transfer request on the grounds that "the player himself wants to challenge for the double title of La Liga and Champions League this season".

In fact, if it weren't for Atletico Madrid's strong performance this season, Mendes saw the team's hope of winning both the La Liga title and the Champions League trophy, and Chelsea, whose form has been up and down this season, not only has it been difficult to defend the Premier League title, but also was beaten by the underdog Barcel in the Champions League group stage, he would have encouraged Diego Costa to switch to Chelsea Football Club in the winter transfer window.

The reason why Mendes values the club's results very much, in addition to Diego Costa's career, is more important is that he can get more commissions in the transfer process.

Now that Chelsea Football Club can make an offer of €60 million at this time, Diego Costa's transfer value is set to rise once he can win both La Liga and Champions League titles this summer. As a result, Mendes will also receive a higher transfer commission.

Although Mendes rejected Chelsea FC's transfer request because he wanted a higher transfer commission, he still declared to Atletico Madrid for the sake of a better reputation: "Although I can get a lot of money from running Diego to Chelsea, if Diego chooses to leave at this time, it will greatly weaken the team's attacking strength and the team's road to the Double will become very bumpy." ”

With the transfer of Brazilian star Diego and the retention of striker Diego Costa, Atletico Madrid are challenged by Real Sociedad on their home turf.

Real Sociedad, who had the advantage of home in the first leg of the match between the two teams, lost 1-3 to Atletico Madrid. Now, having lost the team's top scorer Antoine Griezmann, they have been beaten by the home team without a defense.

Eight minutes into the first half, Diego Costa, with his back to goal, played Juanfrán's long ball back to Alda Turan near the top of the box.

Alda Turan received the ball and fired a long-range shot before sending a through ball into the space on the left side of the box.

Feng Quan, who was running into the box at high speed, first dodged Inigo Martinez's flying tackle with his left foot, then swept the ball sideways with his right foot to dodge a little angle of shot, and then curled a ball with the inside of his right foot to take the lead in the Real Sociedad goal.

Fifteen minutes later, Feng Quan, who switched to the right flank, took advantage of his incisive break to help Atletico Madrid win a direct free-kick close to the corner of the box.

Then, after Miranda, who was ambushed at the back of the goal, headed the ball back to the penalty spot, Diego Costa leaped high to beat Mikel Gonzalez and head the ball into the top left corner of the net.

In the 37th minute of the first half, Feng Quan broke through to the penalty area along the left side to attract the attention of many defenders, and then sent an inverted triangle pass to the left of the penalty area.

Alda Turan received the ball and fired a long-range shot, then took advantage of Bergara's fall to block the line, flicked the ball sideways with his right foot and fired a powerful long-range shot into the top right corner of the net.

After the change of sides, Diego Simeone replaced the three goalscorers Feng Quan, Diego Costa and Alda Turan with Griezmann, David Villa and Diego after 10 minutes of the second half, as Atletico Madrid had to play the first leg of the Copa del Rey semi-final against their local rivals.

Although Atletico Madrid's attacking power in the front court decreased after all three players were substituted, the morale of Real Sociedad was already very low, and in the 37th minute of the second half, substitute Griezmann finally locked the score at 4-0.

It is worth mentioning that Griezmann, who scored the old home goal, did not celebrate, and won a round of applause from the fans.

While Atletico Madrid extended their La Liga winning streak to 13 games, second-placed Barcelona were beaten 3-2 at the feet of Valencia at home.

Although Argentina's Lionel Messi scored a goal in the game and provided an assist for Chilean star A. Sanchez, Alba's two yellows and one red, as well as Pique's low-level mistakes, ultimately gave Barcelona a bitter defeat.

At the same time as Barcelona was hating at home, Real Madrid, who are third in the standings, also drew a tough draw with strong rivals Bilbao away from home.

Compared with Messi's excellent form of delivering a goal and an assist, Real Madrid's top Cristiano Ronaldo's performance is significantly inferior. The Portuguese superstar, who had 10 shots on goal, not only failed to score a single goal, but was even more miserable with only two shots in goal.

After 22 rounds of La Liga, Real Madrid, which opened a 14-point gap with rival Atletico Madrid, basically gave up the competition for the league championship trophy and focused more on the Copa del Rey and the Champions League.

And even Barcelona, who are in second place with 11 points behind, will find it difficult to shake Atletico Madrid's huge lead with 16 rounds of league remaining. 8)
