Iwobi, who was on target in Arsenal’s 2-0 victory against Brighton and Hoves over the weekend, was given permission to sit out of Super Eagles’ drill by Gernot Rohr – as he arrived late afternoon.
Moses, on the other hand, is yet to arrive camp despite his no-show in Chelsea’s 1-0 defeat to Manchester City at Stamford Bridge.
Moses Simon, Chidozie Awaziem, and Ola Aina completed the list of players who did not warm up with the three-time African champions.

Others include Elderson Echiejile, Daniel Akpeyi, Wilfred Ndidi, Uche Agbo, Mikel Agu, Dele Ajiboye, Ahmed Musa Ifeanyi Ifeanyi, Aremu Afeez and Kelechi Iheanacho.
