Roberto Martinez has admitted that he is worried about how his Everton team will combat the threat of Manchester United striker Radamel Falcao at Old Trafford this afternoon.

The AS Monaco loanee is yet to open his account for the Red Devils but, after enjoying goal-laden spells with Porto and Atletico Madrid, Martinez hopes that the 28-year-old waits a while longer before hitting top form.

"He's an out-and-out goalscorer and is someone who is of the highest quality," he told reporters. "He has already accumulated a lot of good experiences in different countries.

"He's been successful everywhere he's been and that's going to be a massive asset to that Manchester United squad."

Kickoff at the Theatre of Dreams is scheduled for 12pm.
