Lucy Beale's killer: The odds

The "Who Killed Lucy Beale?" storyline culminates tonight during EastEnders Live Week, when finally, after nearly a year, the identity of the killer will be revealed.

During a Q & A session this week, Gibbs decided to take a different view of the situation than most, for him it is not Ian Beale or Max Branning, it is the postman Masood, described as the Alpha 'mail' of the Masood family on EastEnders' webste. He did say that he doesn't know who she is, but then cryptically added "the postman?!"

Gibbs has made 17 appearances for the Gunners this season, as he battles with Spaniard Nacho Moreal for a starting place in Arsene Wenger's team.

The 25-year-old spoke last week of the challenges he faces to get into the Arsenal XI, telling Sky Sports: "It has been easier (to get selected) in the past. Now, when you keep everyone fit for a while, obviously you can only fit 11 men on the pitch.

"We need a big squad and we certainly have the squad to compete on three fronts at the moment.

"And we are hungry to defend the (FA Cup) trophy. We are not just going to think that, because we won it last year, it is not in our priorities, because all three competitions are.

"I have to be patient before I play and just take my opportunities.

"We spoke the other week and the boss just said that, since I came back from my injury, Nacho (Monreal) has done well and given me a good challenge.

"He wants me to stay focused and, the more both of us are on the top of our games, the better it is for the team."
