Romelu Lukaku helped spark an Everton comeback against West Brom, but Ronald Koeman insists his side have room for improvement.
Ronald Koeman believes the introduction of Romelu Lukaku as a first-half substitute provided Everton with the impetus they needed to help seal his first victory as manager in Saturday's 2-1 win over West Brom.
Gareth McAuley capitalised on slack defending to put West Brom into an early lead at The Hawthorns and Koeman made a bold move to bring on Lukaku in the 38th minute in place of James McCarthy.
It proved a shrewd move as Kevin Mirallas finished a free-flowing move on the stroke of half-time, before Gareth Barry converted from close range after the break to complete a hard-earned comeback in the Premier League encounter.
