"We lost important players last season during crucial moments of the season and we were not crying or getting excuses about that".
Pogba scored two goals and registered as many assists in United's first four league games, helping them rack up 10 points from a possible 12.
"I will have a meeting with most of the players, with the key players", Koeman said. Pogba has struck up a friendship with Lemar and has sent him Instagram messages suggesting he is brokering a deal to bring Lemar to Old Trafford.
But if there is one weakness in Man United it's their defence and new Everton signings Gylfi Sigurdsson and Sandro Ramirez will be the lead characters tasked with dismantling the home team's rearguard.
Such has been Pogba's influence in the early weeks of the season he was handed the captains armband by Mourinho for United's return to the Champions League in midweek but he hobbled off early on with an untimely injury.
"Squads are for this", Mourinho on Tuesday night, as quoted by ESPN.
Despite Ajax having possession, United still took the lead after 18 minutes, the always-under-pressure Ajax players making an elementary mistake as one of their throw-ins went straight to the head of Juan Mata.
And the claim to have an insider who says the incident has soured the once-close relationship between player and manager. He is playing well, there is a good relationship between the way our striker and the way the team plays.
All this means is that competition for places are bound to intensify in central midfield now that Pogba is out.
Romelu Lukaku is the obvious favourite at 5/6 odds at 10Bet while Marcus Rashford is available at the best odds of 11/8. Pogba will also miss next week's game against Burton Albion in the Carabao Cup, a fixture which in all likelihood he would have sat out anyway, and faces a race to be fit for United's clash against Liverpool at Anfield on 14 October.
"I don't know", said Mourinho when asked how long Pogba would be out for ahead of the Everton game. "Squads are for injuries, squads are for suspensions". We don't cry with injuries.
Fellaini, Herrera and Carrick will share the workload between them.
