If I refer to several sources that I got, in this week's match between Arsenal and Manchester United. Looks like it will be a tough match for The Red Devil. the reason is, several Man United players will be absent in the match against Arsenal, especially the back line players. Actually, I can't confirm the accuracy, but several names will add to the list of those who will be absent. reportedly, Varene will certainly not play in the match against Arsenal. he suffered an injury that is expected to sideline for several weeks.
Agree with you, playing against Arsenal with the remaining squad is quite a difficult match, but however, this incident will provide a big note that Man United is not maximizing their opportunities in the transfer market well. Erik Ten Hag was too self-assured but didn't see the consequences. Without Varane and Luke Shaw is clearly a big loss in midfield and defense. Moreover, Martinez is still in a long injury condition. Like it or not, I'm sure Arsenal will be very happy with Man United condition. Arteta must be aggressive to get full points because the chances of The Gunner are clearly very high.
It seems, you don't know about Lisandro Martinez because the fact is, Lisandro Martinez has been playing in Manchester United starting lineup so far. Also in fact, Martinez has been played by Manchester United from first match this season. Even, Lisandro Martinez also scored an own goal when Manchester United played against Tottenham, of course that was a bad result Thus, Lisandro Martinez is in a healthy condition and is not injured. Thus, it is appropriate for Manchester United to keep playing well in the match away against Arsenal later. Because anyway, just not being able to play Varane in defense, then of course Erik ten Hag should be able to give confidence to other players to be able to enter the starting line up of Manchester United in the match against Arsenal later.
