Lampad said, "With Kenedy, my feeling coming into a big squad with a transfer ban, is that I need to assess the players for as long as I can in pre-season to make sure we pick the right squad.
"If Kenedy continues to show the attitude and play the way he did today he is making a great case to stay having been on loan in recent seasons. Nobody is in or out of the squad or has had a line drawn under or over them. Everybody is competing to stay in it."
Meanwhile, Lampard was again pleased with Mason Mount's showing.
"I thought Mason's performance was really good. It was a continuation of how he played for me last year on loan. His energy is quality even though he hasn't been with us long. We know Mason is part of the first team squad this year, and it's time for him. His qualities will improve even more with the quality around him. Everyone knows the hopes I have for Mason, and he showed a glimmer of what we may see this year and going forward."
