The summer signing from Wigan Athletic came off the bench to head home in the fourth minute of added time at Stamford Bridge and give the Blues a 3-2 win over the Ukrainians.
"We deserved to win the game today. Particularly second half, we dominated the game," Moses told Sky Sports News.
"I came on and only played about 10 minutes on the pitch but it was great to get a winning goal and I thought we deserved it.
"It's been great for me so far so I'm just delighted."
Chelsea are back in Premier League action on Monday when they welcome Liverpool to the Bridge.
