None of those players are currently good enough to start for any of the top 6 with perhaps only Pickford or Gueye who may get into Liverpool's team, possibly Gueye at Arsenal.I think if they're serious about a top 6 spot, then the only players that would be good enough to start for a top 6 team would be Davies, Vlasic, Besic, Gueye, Pickford, Klaasen, Keane. Everyone else would only be good enough with a spot on the bench or as a backup.
Actually I think the team played better WITH Klaasen in the first few weeks than the last few without.
Forget about top 6. This season is about survival which is why I don't think we will have much of a problem attracting a striker. A striker that can then become our backup after we buy a starter in the summer.
