Bukayo Saka is expected to be sidelined for about a month following an injury setback.

He picked up the injury at the 53rd minute of Arsenal's game with Leeds on Saturday, August 23.

He had just completed a sprint and was wrestling with a defender when he felt discomfort in his left hamstring. He was quickly attended to on the pitch for treatment. However, after the game resumed, he signalled to Mikel Arteta, Arsenal's coach, to replace him as he couldn't continue. He was then substituted for Leandro Trossard.

With his current injury, he is anticipated to miss Arsenal’s game at Liverpool on Sunday as well as England’s World Cup qualifiers against Andorra and Serbia next month.

Saka's current hamstring injury in his left leg appears to be less severe than the previous ones he has had in his right leg late last year.

In December last year, during a game with Crystal Palace, Saka suffered a severe hamstring injury, with Arsenal medics fearing a complete muscle detachment from the bone.

Such an injury is considered the most severe, which cannot be managed with rehabilitative therapy; hence, he went through surgery, sidelining him for about a hundred and one (101) days of the pitch.

He missed eighteen matches during his time out until his recovery in April this year.

Saka finished 21st in the voting for last year's Ballon d'Or, won by Manchester City midfielder Rodri ahead of Vinícius Júnior, and asked winning the prize was a target of his, the 23-year-old replied: "It's a dream. I think it's a dream for a lot of players. I'm just working hard to do my best for my team, and any individual awards that come of it, I'll accept it."

Arsenal manager Mikel Arteta urged his players to create their own legacy as they prepare for only their second Champions League quarterfinal in the past 15 years.

Last season, the Gunners were knocked out at this stage by Bayern Munich. Speaking ahead of the match, Arteta said,"Building those experiences is something necessary.

Meanwhile, Saka isn't the only player who suffered an injury during their win match against Leeds on Saturday.

Arsenal captain Martin Odegaard is also doubtful for the match at Anfield as a result of a shoulder injury suffered in the victory against Leeds.

He picked up the injury when he landed on his right shoulder during a challenge.

Ødegaard initially tried to play on but was clearly in discomfort and was replaced by Ethan Nwaneri in the 38th minute.

However, according to Mikel Arteta, during a post-match engagement confirmed it was a shoulder issue, and scans were scheduled the next day to assess the severity.

According to reports, the captain left Emirates with his shoulder in a sling, a confirmation of the pain the injury may have caused him.

The Norway playmaker has not yet been ruled out of the game against the Premier League champions, and there is optimism at Arsenal that neither the 26-year-old nor Saka will be long-term casualties.

There is particular relief regarding Saka, who missed three months of last season with a hamstring injury.

Arsenal have a much deeper pool of attacking talent this season, though, having signed Viktor Gyokeres, Noni Madueke and Eberechi Eze this summer.

Gunners manager Mikel Arteta also has Gabriel Martinelli, Leandro Trossard, Ethan Nwaneri and Max Dowman to mitigate the absences of Saka and Odegaard.
