Palmer wore the armband during Chelsea's dominant 7-0 FA Cup victory over Port Vale at Stamford Bridge, a match in which Adarabioyo also found the net.

Speaking to Chelsea's official website after the win, Adarabioyo emphasised the club's determination to succeed in the historic competition.
"That was the objective going into the Port Vale game, that we get ourselves to Wembley, so we were pleased to do that," he stated.
"The FA Cup is a huge trophy and, as long as you're in it, then you're in it to win it. That is what we're trying to do."
The defender also spoke highly of Palmer's leadership, highlighting his influence on the squad.
"He's my guy," Adarabioyo said with a laugh. "He's always encouraging me and I'm always encouraging him, so it was nice."
"He leads by example," he continued. "You can see through his performances that he is one of our leaders and one of our best players. So it was nice to see him get the armband."
With the cup tie behind them, Adarabioyo's attention has turned to a crucial Premier League fixture against his former club, Manchester City.
He stressed the importance of securing a positive result to aid Chelsea's pursuit of a UEFA Champions League spot.
"We're just looking forward to the game and getting the job done against Manchester City. Hopefully, we get the three points, but we need to prepare now and that is our focus," he added.
