ARSENAL could be handed a HUGE boost in their quest to overcome Real Madrid in the Champions League quarter-finals.
It comes after Uefa have opened an investigation against Kylian Mbappe and three other Real stars.

Antonio Rudiger, Vinicius Junior and former Arsenal loanee Dani Ceballos join Mbappe in facing disciplinary action.
A Uefa Ethics and Disciplinary Inspector has been appointed to investigate allegations of “indecent conduct” by all four players.
The unspecified incidents occurred during Real’s second leg last-16 victory against city rivals Atletico on March 12.
Their punishment, if found guilty, is not yet known.
But IF they are banned, it could be a huge advantage for Arsenal, who are missing several key players through injury.
The Gunners host the 15-time European champions in just under a week on Tuesday 8, with the return leg the following Wednesday.
And Vinicius and Mbappe are joint-highest in club goals in the Champions League this season (seven goals apiece).
Madrid advanced to the quarterfinals in a controversial 4-2 shootout after Atletico won the second leg 1-0 to tie the aggregate score at 2-2.

Tensions were high at the Metropolitano before, and after, Julian Alvarez’ spot-kick was disqualified by VAR.
Vinicius was the most high-profile case, as he reportedly took six “shots” at Atleti supporters during and after the clash.
Rudiger aimed a throat-cutting gesture at Atleti supporters, while Ceballos is alleged to have “cut his sleeves” as an act of provocation.
And in regards to Mbappe, he is claimed to have touched his private parts.
Diego Simeone was banned for grabbing his bits during a Champions League match against Juventus.
It remains to be seen whether Rudiger, Ceballos, Vinicius or Mbappe are charged by Uefa over these incidents.
