Koeman, whose team has made a slow start to the campaign and visits United on Sunday, said replacing Lukaku was always going to be a huge ask.
"The way we play, the way we think football, the way the fans think, the empathy between the fans and the team, the confidence levels of the players, the footballing level I am happy with what we've done so far".

"The selling club decides the amount and the buying club pays or doesn't pay". With Romelu my club chose to pay and they got him'.
He faces a major challenge, though, to match Rooney, who left Everton for United and became their all-time record scorer, with 253 goals during his 13 years at Old Trafford, winning the Champions League once and the Premier League five times.
