There's something about the Tyneside air that doesn't suit Chelsea. Just one win in their last seven visits to Newcastle doesn't bode too well for the continuation of their recent good form this weekend.
They've become unstuck at St James' Park so often under various managers in the past few years that we're entering hoodoo territory.
In 2013, under interim manager Rafa Benitez, Chelsea threw away a 2-1 lead by conceding twice to Moussa Sissoko as Demba Ba, jeered on his return to the north-east barely a month after moving, had his nose broken by Fabricio Coloccini's high boot.
