Muller, who played for a club in Kerala, was scheduled to fly home by Kenya Airways flight when the lockdown
was announced and he found himself stranded at the Mumbai airport.
"He would spend his time at the airport's fancy artificial gardens and somehow buy food from stalls and pass his time with the airport staff. Muller told me the airport staff was very helpful," Yuva Sena office-bearer Rahul Kanal said.
A security officer at the airport gave him mobile phone to call his family back home. A Twitter user brought Muller's plight to the notice of Maharashtra Tourism Minister Aaditya Thackeray following which Kanal reached out to the footballer and helped him move into a hotel.
On Saturday, Muller thanked Thackeray and Kanal for their help.
"Thank you Aaditya Thackeray, Rahul Kanal. Thank you very very so much. I appreciate what you have done. Salute," he said. Kanal in a tweet said when he met Muller at the airport, the latter cried with happiness.
"Have no words to salute his willpower and fight for survival in such circumstances at this age," Kanal said.
An official at the Mumbai International Airport Ltd said the footballer was provided all help.
"All personnel at the airport, including from MIAL and CISF, gave him every possible help during his stay at the airport. Besides food, he was also allowed to use the airport WiFi network to make calls. Airport staff would recharge his phone at their own expense," the official said.
