West Ham boss David Moyes was delighted after their 4-0 win at Bournemouth on Sunday.
Michael Antonio, Lucas Paqueta and captain Declan Rice struck before halftime before substitute Pablo Fornals completed the rout in the second-half.
Moyes said, "Probably one of our best weeks. We scored four in this game and the midweek game.
"I glad we set the tone early, we got a great start and it gave us something to hang onto.
"We got such a result from Arsenal and then to have the quarter-final was a big thing for us and the players took it into today's game and they could have taken fatigue into the game, but overall the team put in a very good performance.
"Pablo Fornals is such a great team player and he has been big part of how we have got through the levels. It will give him such huge confidence. I haven't seen the goal back but it's things people like to see."
On the Irons' recent form, he added: "We look more clinical and Antonio got another goal today and Paqueta got a goal in open play. Overall we are really pleased and what we can build on. We certainly didn't start the season well so hopefully we can finish it well."
