Former Arsenal goalkeeper Jens Lehmann has offered a reward of £2,000 to anyone who can return his bag that was stolen.
The German sportsman is said to be in London this week for Arsenal's Champions League clash against Bayern Munich at the Emirates Stadium.
The 44-year-old took to social networking website Twitter to reveal that his bag was taken from his parked car near Selfridges in the capital.
Lehmann wrote on Twitter: "My dear followers, I am asking for some help. My bag has been stolen today out of a red fiat500 at Duke Street, London, W1, near Selfridges.
"If the back and all personal contents can be returned to me by Wednesday, I will pay 2.000 pounds. Please contact me by Twitter!!!"
Lehmann was also part of BT Sport's coverage of Arsenal's 2-1 win over Liverpool in the FA Cup fifth round last Sunday.
