The 24-year-old attacker came on as a substitute in the 65th minute to find the nets two minutes before the final whistle.
Mohamed has scored four goals in 26 appearances with Galatasary in the Turkish league so far this season, booking a regular place in the team’s lineup in all competitions.
The Egypt international joined Galatasary from Egyptian side Zamalek last January for a one-and-a-half-season loan deal with an option to make it permanent after paying $4 million.
Mohamed made an impressive start with Galatasaray, scoring 14 goals in 44 appearances in all competitions since joining the team.
He was close to joining French side Bordeaux this summer but he failed to complete the move due to differences between Galatasaray and Zamalek.
Galatasary coach Fatih Terim announced early last week that he held talks with the club’s board to discuss the future of the Egyptian striker with the team.
“We held a meeting with club’s board and decided to officiate the contract option of Egyptian striker Mostafa Mohamed,” Terim told a press conference.
