Everton boss Rafael Benitez stressed the need for the Toffees to improve in defence following their Carabao Cup exit at the hands of Sky Bet Championship side QPR.
Tuesday's third-round tie at the Kiyan Price Foundation Stadium saw Benitez's men crash out on penalties after a 2-2 draw.
Everton, who were beaten 3-0 at Aston Villa in the Premier League last weekend, twice trailed to Charlie Austin headers, with Lucas Digne and Andros Townsend netting equalisers.
