Everton boss David Moyes admits they must be wary of Sebastian Larsson's threat for Sunderland today.
The Swede's delivery from wide areas is also potent, as is that of Kieran Richardson - as was proved by two assists in the midweek win over QPR.
Moyes told evertonfc.com: "I think you have to be careful not to concede free-kicks in silly areas against someone (Larsson) with that ability.
"I watched the game against Blackburn - where Martin had just taken over - and they were a threat. I think they have scored a couple again (against QPR) from set-pieces.
"They have great delivery with both Richardson and Larsson, so we will have to be careful to give too many away."
