Fosu-Mensah has started 10 Premier League games this season and in this final match of 2017 he took the plaudits for his performance up against German winger Leroy Sane.
The Eagles fans showed their admiration for the defender against the league leaders in the contest as they casted their votes on the club’s twitter channel to vote for their number one from the afternoon's action.
Just under 6000 votes saw Fosu-Mensah take 73% of the poll for the 19 year old.
Congratulations Timothy.
