Henrikh Mkhitaryan and Eric Bailly were both part of the Manchester United squad that trained under Jose Mourinho on Wednesday afternoon.
Mkhitaryan and Bailly joined their new teammates for the first time since completing moves from Borussia Dortmund and Villarreal respectively in this transfer window.
Also part of the main group was fit-again Luke Shaw, who has recovered from a broken leg, while Memphis Depay, Daley Blind, Phil Jones, Timothy Fosu-Mensah and Michael Carrick also took part in the session.
However, those that took part in Euro 2016, including fellow new signing Zlatan Ibrahimovic, have not yet returned to pre-season training due to their international commitments.
Man United, now under the management of Mourinho, will kick off their pre-season campaign with a trip to Wigan Athletic on Saturday afternoon.
