The Newcastle United icon says there is only one way things are heading at the moment.
Newcastle have sat in the relegation zone for the majority of the season so far and their 6-1 defeat at Manchester City on Saturday afternoon hardly made matters any easier in that regard.
And, after analysing the stark contrast between their first-half performance and the second-half capitulation they displayed at the Etihad Stadium, Shearer told Match of the Day: "Newcastle will get relegated if they keep playing like this."
As things stand, it is completely plausible that Newcastle can or will go down.
There are no worse teams than the Magpies, Sunderland or Aston Villa right now. Even the fact Chelsea are struggling is worrying for a club like the St James' Park outfit as the Blues will realistically always pull it round.
Steve McClaren being sacked at some point this season looks a given but who next? Newcastle's recent track record has been to hire English managers with average to no track records. It will need a really fresh appointment to shake things up on Tyneside.
