At 6ft 8in and recently acquired on loan from Monaco, the Ivory Coast international Lacina Traoré represents the exotic solution to Everton's striking shortage. The diminutive, Irvine-born Steven Naismith is proving the effective one.
Both forwards were on the scoresheet as Roberto Martínez maintained his hold on the FA Cup with victory over his former club Swansea City. The Everton manager was helped to the quarter-finals by careless Swansea defending and wholesale changes from the interim manager, Garry Monk, but the Scotland international's contribution was ultimately decisive.
Naismith was on the field for 30 minutes, during which time he scored for the fourth time in five appearances, won a penalty and departed with concussion after a blow from the defender Jordi Amat.
It encapsulates the 27-year-old's fluctuating career at Everton that he had no recollection of his latest impressive cameo but his importance has not been lost on Martínez.
"He was OK when he took the knock but then he couldn't remember what happened," said the Everton manager, who saw his Scottish substitute score in the "defining" Premier League win over Aston Villa recently.
"He didn't remember scoring a goal so we told him it was from 40 yards. We will have to keep him under observation for 24 hours but I'm really pleased for him. He's a gem of a boy and is really enjoying his football."
Naismith's energy, commitment and clinical touch were invaluable for Everton. Martínez's team had the luxury of an early goal from the debutant Traoré against weakened opposition but only in the second half did they find the urgency and concentration to capitalise.
Martínez forewarned about handling expectation, and Everton's must have risen when Monk announced eight changes to the Swansea side that started at Stoke City in midweek, but the home side laboured before their strong recovery.
"I gave the players two clear instructions at half-time," explained Martínez. "One was to enjoy the game a bit more. We were thinking more about the outcome rather than being on the ball and moving the ball properly.
"The other one was that we were getting ahead of the ball too quickly. We had to support the man on the ball more. Swansea's energy levels were terrific and they were closing us down.
"We dealt with that well in the second half, we were too cagey in the first, and it was very satisfying just to get the win and get into the next round."
Monk made no apologies for his team selection, with Napoli to come in the Europa League on Thursday and Premier League safety essential. Swansea's performance for 65 minutes vindicated the new manager's stance, with Álvaro Vázquez wasting an excellent chance to open the scoring after 30 seconds and the visitors unsettling a nervous Everton defence throughout, but defensive lapses proved costly for the Welsh side.
Sylvain Distin was instrumental in the breakthrough from a Kevin Mirallas free-kick. The Everton defender won the header at the back post, then had the presence of mind to pick out Traoré after Kyle Bartley failed to clear. At close range, and facing away from goal, the on-loan striker flicked out a telescopic leg to heel the ball past Ashley Richards on the line.
Any thoughts that Everton would cruise into the quarter-finals were dispelled as Swansea reacted better to Traoré's goal and they were back on level terms courtesy of a fine header from Jonathan de Guzmán. Everton were under pressure after Steven Pienaar carelessly conceded a corner. Though cleared, Swansea patiently retained possession and Roland Lamah floated an inviting cross over Everton's central defenders for De Guzmán to complement an intelligent run into the area with a powerful header beyond the goalkeeper, Joel Robles.
Pienaar almost atoned immediately with a superb touch to release Leighton Baines and a shot against the bar from the return pass, Traoré forcing Gerhard Tremmel into a decent save from the rebound.
It was only after the interval, however, that Martínez's team showed the energy to stretch and trouble Swansea and ultimately eased their way into the last eight.
There appeared more belief and less apprehension from Everton from the restart as Ross Barkley tested Tremmel from the edge of the area and Pienaar put a diving header just wide from Seamus Coleman's right-wing cross.
But it was the introduction of Naismith for the tiring Traoré that changed the course of the tie. Within five minutes of coming on, the Scotland international scored when he capitalised on a poor back pass from Neil Taylor and slotted the ball under Tremmel.
Naismith was then first to a loose ball inside the Swansea area after a good challenge from Baines and was scythed down by Richards for a clear penalty. Baines duly obliged with his 15th successful spot-kick in 16 attempts for Everton.
