'We know him really well', Koeman said about Romelu Lukaku. 'He's one of the best strikers. I mentioned several times last season he's a great finisher. I hope that we know how we have to defend against him'.
The Belgian international scored 20-plus goals in each of his three seasons with the Toffees before a big-money move to Old Trafford, and the Dutch manager insisted Everton will have to tighten up at the back to deal with the threat of the in-form striker.
'There are a lot of individual qualities in the players around him [at United]. In the box he's really dangerous, he's fast, he's strong', the Everton manager added.
He concluded by firing a warning for his players: 'If we defend how we've defended in the last few games then maybe it will be his afternoon'.
