"Nobby is a very good player, and a very important one to us, but against West Ham we decided to play with only one winger," said Sir Bobby.
"We tried to be a little more solid in midfield so I did what I had to do. We knew whoever played out wide would be OK.
"I brought LuaLua on at 2-1 down because you never know what he might do. Had it been 2-2 or had we been winning then I would have brought Nobby on to help secure it."
