The Football Association are set to work with a lip reader as part of their ongoing investigation into an incident between Arsenal defender Gabriel Magalhaes and Jordan Henderson during Liverpool's 3-2 defeat at the Emirates on Sunday.
The pair clashed late in the second half after Henderson was evidently aggrieved with referee Michael Oliver's decision to award a penalty when Thiago Alcantara and Gabriel Jesus came together. Henderson and Gabriel stood face-to-face, while Bukayo Saka composed himself ahead of taking the penalty, before being separated by Reds defender Kostas Tsimikas.
Saka ultimately converted his spot-kick to hand the Gunners a slender victory over Jurgen Klopp 's side, who had twice come from behind in north London before falling to defeat.

At this stage of proceedings, it remains unclear what Henderson said to the Brazilian defender to cause such a fierce reaction and later led to Granit Xhaka exchanging words with the Liverpool captain. However, after Oliver was made aware of the exchange he swiftly cooled down the two teams' tempers before speaking to both Klopp and Mikel Arteta on the touchline.
It was also revealed that Oliver subsequently spoke to the game's fourth official Andy Madley, who was seen taking notes of the referee's timeline of events, which would later be used if the FA decided to pursue an official investigation.
Gabriel and Henderson could be seen speaking to one another after the full-time whistle and the Brazilian's international team-mate Roberto Firmino was also in attendance. It is unclear whether the conversation between the duo was held in order to clear the air of any earlier misunderstanding over an exchange of words that had clearly angered the defender.
Klopp didn't comment on the incident in his post-match media duties. Meanwhile, Arteta played down the event in his post-match press conference as he declared "whatever happens on the pitch, stays on the pitch."
Quickly after both managers had completed their media duties, the FA confirmed they would be looking into the incident, saying in a statement: "We are aware of an incident that took place during the match between Arsenal and Liverpool. We are in dialogue with the match officials and will review the details of the incident."
Additionally, the Liverpool captain had been pencilled in for post-match interviews after the game but was later taken off those duties.
On Tuesday afternoon, Sky Sports revealed that the FA is reviewing the referee's report from Sunday's game and simultaneously gathering information from Henderson and Gabriel. Keeping in line with the FA and Professional Game Match Officials Board protocol, Oliver also spoke to both players after the match in what is the first stages of any potential disciplinary process.
It is likely the governing body will also gather eyewitness accounts from those close to the action in order to seek clarity on the situation.
