Keown wrote in the Daily Mail: "I fear for West Ham. There were massive inconsistencies last season. They didn't manage back-to-back wins all campaign, Jussi Jaaskelainen had to make more saves than any other player and they won just three times away. Also, they haven't added much to their squad.
"Their biggest signing is Andy Carroll but he was there last season, he struggles with injuries and he scored just seven times.
"Sam Allardyce knows how to get success from a team and while they don't play any of the top four until October, they'll need a good start or the confidence could quickly drain away."
