Moses overjoyed with winning strike
Chelsea, who were beaten by Shakhtar at the Donbass Arena two weeks ago, gave up the lead twice at home to the Ukrainian champions before Moses rose to convert Juan Mata's header with just seconds remaining.
The defending champions were outplayed for long periods by the visitors, but now find themselves level with Shakhtar on seven points at the top of Group E.
"We deserved to win the game today, particularly second half, we dominated the game," Moses told Sky Sports after the game.
"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.
"The three goals I've scored for the club have been headers, it's been great for me so far so I'm just delighted."
Fernando Torres gave the home side the lead after just six minutes, when he charged down goalkeeper Andriy Pyatov's attempted clearance, but the lead proved short-lived, as Willian soon hauled the visitors level.
Pyatov again gifted the home side the lead when he rushed out to intercept a long ball forward, only for Oscar to pounce on the clearance and hit a stunning 45-yard half-volley into the empty net five minutes before the break.
"At the start, he (Pyatov) was bad at kicking out from the back and we capitalised from it. Oscar scored a goal, but we just wanted to do our best and we're delighted with the three points," Moses said.
Meanwhile, Gary Cahill complimented the attacking talent the visitors possess, and conceded Chelsea probably would have taken a point heading into the clash.
"We knew after we played them in the first game and they were fantastic tonight," Cahill said.
"At times it looked like they played five up front, the full-backs pushed forward and at times it was end-to-end stuff but I thought we did well, we played some good stuff. But they're a fantastic team and it's a great three points for us tonight."
