Murray Wallace fired Millwall to a controversial 3-2 FA Cup fourth-round victory over Premier League opponents Everton. Defender Wallace calmly scored a stoppage-time winner as Millwall rallied from 2-1 down to shock the Toffees, with the hosts profiting from Jake Cooper's disputed equaliser. Cooper appeared to nudge home Millwall's second goal with his arm, but referee Michael Oliver still awarded the goal despite consultation with his assistants. Richarlison's opener was quickly cancelled out by Lee Gregory's neat header. Cenk Tosun put the visitors ahead once more, but Cooper barged his way to another rapid Millwall equaliser. Everton were left to rue another lacklustre performance when Wallace sent the Den into raucous celebrations and Millwall storming into the fifth round.
