Leicester are still rooted in the relegation zone, leaving Leicester Newcastle to beat Magpies 4-0 on Sunday, while West Ham’s Champions League ambitions were damaged by a 0-0 draw at Burnley.
Despite being hit by Corona virus The outburst that left Brendon Rogers without seven players, Fox gave Eddie Howe a second reminder of the task he had to face to keep Newcastle on top flight as Yori Tillemans struck twice at King Power.
Howe will be able to call on Saudi sovereign wealth fund resources in the January transfer window and results elsewhere this weekend mean they are only three points behind in safety.
But Newcastle will face Liverpool, Manchester City and Manchester United in their next three games and, in this form, will be lucky to be able to avoid a run without another serious hit to their goal difference.
Leicester have won just two of their previous nine games in all competitions and were knocked out of the Europa League by Napoli on Thursday. However, before half time James Madison approached Javier Mankillo to win a penalty and he got the necessary break.
Jamie Verdi was watching from the bench, Tylemans taking responsibility for opening the scoring seven minutes before half time.
The form of Patson Daka has earned him a place in the Premier League ahead of Verdi in recent weeks and the easiest task for Zambian was to roll into his seventh goal of the season to double Leicester’s lead with a selfless pass from Harvey Barnes.
The Tillemans completed a great team move for their second half of the afternoon before Madison’s fine finish added more time to Newcastle’s pain.
The victory lifted Leicester to eighth and returned to the fight for a place in the top four when West Ham lost their chance to extend their lead over the chasing pack. The Hammers have won just one of their last five league games since Nick Pope frustrated David Moyes’ men at Turf Moore by saving a lot.
West Ham are one point ahead of fifth-placed Manchester United, but Tottenham, who are out of action this weekend due to their own covid outbreak, are just two points behind with two games in hand. Even one point does little to help Burnley’s hopes of survival as he is 18th, but now only two points behind in safety.
