Arsenal are without Kai Haverts and Gabriel Jesus for the rest of the season. In addition, Bukayo Saka is injured. This is the situation for Mikel Arteta when it is fighting hard to cut Liverpool’s lead in the Premier League and very important Champions League matches await. Something must be done. Roberto Firmino has been linked with an emergency return for Arsenal, some supporters believe it is also relevant to call on the former Chelsea player they hated.

Few players have provoked opponents and supporters (and their own coaches) as much as Diego Costa in the Premier League, 2014-17.

The injury situation at Arsenal has given Nwaneri opportunities, with the 17-year-old developing in every game. Still, the Premier League title is not won with a 17-year-old as one of the solutions at the top.

This week, Arsenal supporters have posted a message with “what about Diego Costa?”

The Brazilian 38-year-old has scored a total of 161 goals in 376 appearances as a striker, in the Chelsea shirt he was behind 59. What Costa has shown is that he (apart from a tame round at Wolverhampton with 1 goal) finds goals no matter what shirt he wears.

William Gallas has worn both the Arsenal and Chelsea shirts and comments on the idea of a Costa as an emergency solution at the Emirates.

“Diego Costa is a free agent and he’s a big character, which can be good for your squad when you need to lift your spirits,” Gallas begins to Caughtoffside.

“But I could see him colliding with Mikel Arteta. He will not fit into the atmosphere of the club, and I think it will go the wrong way. Even if they need a striker… He’s of a different generation, and I think it would be difficult for him to fit in,” Gallas concludes.
