Martin Angha is in line for a shock first team call at injury-hit Arsenal.
The Daily Mail says Arsenal are set to face league leaders Manchester City in 10 days' time without any recognised full backs.
Arsene Wenger may need to promote 17-year-old Swiss defender Angha to the first team to face Everton on Saturday because he is so short of options on the left and right of defence.
Andre Santos, 28, injured his left ankle in Tuesday's 3-1 defeat by Olympiakos and last night revealed on Twitter that he will be out for three weeks.
With Kieran Gibbs still a fortnight away from returning from last month's hernia operation, Thomas Vermaelen will have to move from central defence to plug the gap and Laurent Koscielny and Per Mertesacker will play together in the middle of the back four.
