David Moyes insisted he wouldn't put his name to West Ham's first-half performance in their 4-0 defeat at Everton on his return to Goodison Park.
The defeat means Moyes has suffered five successive defeats back at Goodison as an opposition manager, without scoring a goal, having seen his teams ship 12 goals in those games.
West Ham looked likely to get back in the game at 2-0, but Aaron Cresswell was denied by the crossbar, and Manuel Lanzini saw his penalty saved by Jordan Pickford.
Rooney then took centre stage, as he scored a stunning strike from inside his own half, before Ashley Williams completed the rout.
"The second half at least, I could put my name to the performance," Moyes said. "I didn't want to put my name to the first half, that was for sure.
"We made changes at half-time, it made us better and look, tonight we weren't good in the first half, so we didn't deserve anything, but I thought when we needed small things to go for us, they didn't.
"I mean, Wayne's penalty was saved by Joe Hart, but it came back to him. Tonight, Lanzini's was saved, so from that point of view small things like that didn't go for us.
"I thought actually for the third goal, Michail Antonio drove into the box and I think he needed a decision whether to shoot or slide a pass, he made a pass and it was a bad pass. It went up the pitch and launched it clear and Joe [Hart] came out and before you know it, we're 3-0 down and I didn't think we deserved that scoreline, not on that second half performance."
Moyes refused to be drawn on the Everton managerial situation, with Sam Allardyce set to take over, insisting whoever was in charge would have overseen victory.
"I think I was more interested in how West Ham performed," Moyes said. "Whether Sam or 'Unsie' was in charge, it wouldn't have made any difference. We had to perform and we didn't perform.
"We didn't perform well enough in the first half. As I've said, I think the game could have changed if we'd got the penalty back to 2-1, because there was no doubt that we were on top, but we didn't do so."
