Soccerway has made quite a mess regarding Mohamed Hammoud; I'll try to clear it up:
Mohamed Hammoud (goalkeeper) -> Mohamad I Hammoud
Full name: Mohamad Hassan Hammoud
12/13: Ahed 0 apps 0 goals
13/14: Ahed 0 apps 0 goals
13/14: NOT at Nejmeh
rest is correct
Mohamed Hammoud (right-back) -> Mohamad II Hammoud
Born: 1 May 1984 (not in 1988)
Full name: Mohamad Mostafa Hammoud
01/02 to 08/09: Hikmeh La Sagesse Beirut
14/15: Nejmeh (16 apps 2 goals)
15/16: Nejmeh (16 apps 0 goals)
16/17: Nejmeh (15 apps 0 goals)
17/18: Al Shabab Al Arabi (15 apps 0 goals)
end of career, not at Shabab Al-Sahel
Mohamed Hassan Hammoud -> Mohamad III Hammoud
Full name: Mohamad Hassan Hammoud
06/07 to 13/14: Ansar
14/15: Safa (21 apps 0 goals)
15/16: Safa (11 apps 0 goals)
16/17: Akhaa Ahli Aley (17 apps 0 goals)
17/18: Akhaa Ahli Aley (16 apps 0 goals)
18/19: Shabab Sahel (20 apps 0 goals)
19/20: Shabab Sahel (3 app 0 goals; cancelled season)
20/21: Shabab Sahel (ongoing)
Hopefully this is clear enough. I've also explained this to Soccerway who should fix all the profiles.
