A goal against Chelsea would take Beckford into double figures in what is his maiden campaign at the level, and earn him parity alongside the injured Louis Saha as the Club's top scorer.
Cahill himself is stuck on nine goals but his involvement in the Blues' Premier League finale remains in doubt because of an ongoing foot injury.
Cahill told evertontv: "Beckford is on nine goals and that is fantastic. Hopefully he can get his 10th at the weekend and end up as the top goalscorer as that would be really good for him. It would be an achievement in his first season."
