Havertz tore his hamstring during training in Dubai and Arsenal have confirmed he will not return until next season.
To make matters worse, Arsenal youngster Myles Lewis-Skelly is now facing a suspension after being shown a straight red card against the Hammers, thus ruling him out of Wednesday’s huge clash away at Nottingham Forest.
Arsenal have since revealed the extent of Tomiyasu’s injury nightmare, stating the defender’s recovery and rehabilitation programme is expected to be completed towards the end of this year.
Arsenal suffered a potentially damaging defeat to West Ham at the weekend as they failed to apply more pressure on Liverpool in the Premier League title race.
Though, he has vowed to not give up: “I’ve had a surgery on my knee few days ago and I’ve already started my rehab to do what I love the most again,” Tomiyasu said in an Instagram post.
