The Football Association have contacted Brentford to ask for their help in verifying Everton manager David Moyes' claim that a Bees supporter threw a bottle into the away end after last night's Carling Cup clash at Griffin Park.
The home crowd spilled onto the pitch moments after Phil Jagielka's penalty miss had knocked the Barclays Premier League side out of the competition.
It was then that Moyes claims to have seen a Brentford fan launch a bottle into the Everton supporters' end. The FA are keen to follow up Moyes' claim although it is understood that a full investigation is not being considered at the moment.
An FA spokesperson said: "We are aware of the claims made by Mr Moyes and have contacted Brentford to ask for their observations into the matter."
Moyes was left fuming at the alleged incident, with the Scot having to hold himself back from confronting the person he claims was responsible.
The Everton boss said: "I saw a fan throw a bottle into our supporters. It was terrible. I said to him `I saw your face. I saw who you were'."
