I thought the same last season. They were the worst team we played. Annoyed we lost to them this season, but they generally defend quite well for a team near the bottom and every so often Benteke, Weimann or Gabby does something to win a game. I think that will be enough to keep them up.
I get the impression Lerner wants to recoup much of the money he spent with Oneil by spending very little and remaining in the Premiership. Once he has done that he will probably run in like a business, which will be good for them. The question is for how many seasons can they keep treading water.
