The Asian Cup kicked off on Saturday, with hosts the United Arab Emirates drawing 1-1 against Bahrain.
Group C kicks off later today (Monday) with Newcastle United involvement in the competition for the first time.
Ki Sung-yeung is expected to start for South Korea as they take on the Philippines in their opening group game.
On Wednesday it is the turn of Group F, with Yoshinori Muto potentially playing for Japan as they take on Turkmenistan.
The group games end on Wednesday 16 January for Ki Sung-yeung and the Thursday 17 January for Yoshinori Muto – but both players/countries are expected to easily qualify from the group stage.
Last 16 knockout matches will be played between 20 January and 22 January, though a major surprise is both countries don’t reach the last eight as a bare minimum, with quarter-final games to be played Thursday 24 January and Friday 25 January.
That would mean even if knocked out at that stage, the first Newcastle match either would be available for would be Spurs away on Saturday 2 February (Newcastle match schedule below).
Newcastle face Man City at home on Tuesday 29 January but with travel and recovery time, it would be a big surprise if Rafa Benitez risked either player.
Not ideal for Newcastle United purposes but good luck to the two players in the Asian Cup, which is the equivalent of the European Championships.
