Lucas Paqueta was beginning to justify why West Ham paid a hefty transfer fee for him, after a challenging start to his career in England.
The Brazilian was expected to elevate the team’s performance, as they spent £51 million plus bonuses to acquire him.
After scoring his first Premier League goal from open play against Newcastle, the midfielder was substituted during the match against Chelsea due to a possible shoulder injury.
Paqueta attempted to continue playing but eventually had to be replaced by Tomas Soucek. Fans of West Ham are hoping for a quick recovery for the Brazilian.
The extent of the injury has not yet been revealed, but David Moyes hinted that it might be a dislocated shoulder.
The estimated recovery time for a dislocated shoulder that requires surgery is 6 to 12 weeks, while a non-surgical injury can be healed in a few weeks.
Speaking after the game, Moyes said: “Losing Paqueta was a blow but we don’t know the answer yet.
“I don’t know, I haven’t asked the medical team, but obviously, it’s a shoulder injury.
“I don’t know if he’s popped his shoulder or if it’s just the way he feels, I’ve not got the answer to that yet.”
Meanwhile, West Ham captain Declan Rice said: “Lucas, I think his shoulder popped out, to be fair. So, he was in agony.”
