Wesley Fofana has jokingly warned Noni Madueke to "protect his ankles" as the duo became "enemies" following the England international's move from Chelsea to Arsenal.
The 23-year-old signed a five-year contract withthe Gunners earlier this week after they agreed a £50m deal with the Blues.
Madueke joined Chelsea from PSV Eindhoven in January 2023 and made 92 appearances for the Blues under a selection of managers, including Graham Potter, Mauricio Pochettino, and Enzo Maresca, and helped the club win the UEFA Conference League last season.

However, Madueke's former Chelsea team-mate Fofana has warned the forward that there will be no time for friendship when the two sides face off in the Premier League next season.
Writing under Madueke'srecent Instagram confirming his move to Arsenal, Fofana said: "See you on the field, protect your ankles. We are enemies now. All the best, mon frère."
Madueke's first appearance as an opposition player at Stamford Bridge could come on November 29 when Arsenal travel to West London.
"Humbled and blessed to be here. Thank you to everyone that made this possible," Madueke wrote on Instagram.
"I can't wait to get on the pitch and start to repay the faith shown in me. It's going to be so special."
Meanwhile, Mikel Arteta said: "Noni is an exciting and powerful young player, with his performances and numbers in recent seasons being of consistently high quality.
"He is one of the most talented wide forward players in the Premier League.
"At just 23, Noni already brings experience of club and international football, and he knows the Premier League very well."
