stop conceding goals

Hi
I have a major problem I concede to many goals how can I concede these by tactic or formation??
Any help would be great

Generally regardless of who you have and what formation, 4-4-2, and 4-5-1 are decent defensive formations. You want to try and play more narrow, and if you want the other team to stop having momemtum telling them to get stuck in is usually a good idea. Again not much other help can be given until we all know the details
