Hodgson admits derby win vital for West Brom
Albion moved out of the bottom three thanks to the result.
Hodgson admitted: "It was a very important game and it was excellent to get our first home win of the season.
"It was also important to get our third clean sheet from eight games. That's more than the two for the whole of last season.
"If we keep three clean sheets every eight, we'll be fine."
