Arsenal is urgently looking for a replacement for Saka.
Arsenal are facing a major headache as Bukayo Saka faces a long-term spell on the sidelines following hamstring surgery.

Brentford's Bryan Mbeumo has emerged as a top target and the Gunners are pushing hard to complete a deal in the January transfer window, according to multiple reports.
A hamstring injury has plagued Bukayo Saka this season, forcing him out of the game against Crystal Palace. This is the third time he has suffered the problem and surgery is seen as a solution to the problem. Saka himself has updated fans on the injury via a social media post, stating his determination to come back stronger. However, his absence will certainly be a big loss for Arsenal.
"He had an operation and everything went well," said Arteta. "But unfortunately he will be out for weeks, many weeks. I think more than two months." The news has dealt a blow to Arsenal's ambitions this season, with Saka one of their most important players with nine goals.
In that context, Bryan Mbeumo has emerged as the most likely option to replace Saka. The 25-year-old Cameroonian striker has been impressive at Brentford with 13 goals in 20 Premier League games this season. It is worth mentioning that Mbeumo was also on Arsenal's radar at the end of the summer transfer window last year. Now, with Saka absent, Mbeumo has become an even more priority target for the Gunners.
Not only is Mbeumo good at scoring goals, he is also highly appreciated for his versatility, ability to create breakthroughs and speed, factors that are very suitable for Mikel Arteta's football philosophy. The similarity in playing style as well as position on the field helps Mbeumo to fill the gap left by Saka, at the same time bringing diverse attacking options to Arsenal.
The Mbeumo deal is not only a necessary addition to the squad, but also an affirmation of Arsenal's ambition to compete for the title this season. With the determination of coach Mikel Arteta, fans have the right to hope that the Gunners will soon have the signature of the Cameroon striker in this January transfer window.
