Hodgson says West Brom must buy this summer
Hodgson warns they can't afford to stand still.
"We're going to have to make certain we continue to improve our squad because it's about quality players," said Hodgson.
"A lot of players who have helped us over the last couple of years were players who actually came into help the team get out of the Championship.
"There is work to do. It won't be easy to find the quality that we need because the players we've got are not bad at all but if we're going to add some it would have to be adding that bit of quality.
