"Every player wants to play, but I fully respect the manager's decision," said the striker after scoring Celtic's goals in a 3-0 win over Motherwell. "I'm behind him 100%. We were really unlucky the result did not go our way.
"We were just really unlucky at the end of the game," McDonald told BBC Sport. "Okay, they hit the post and the bar, but we rode our luck and we were a bit unfortunate at the end and I'm just glad we have picked ourselves up and had a good result today."
"There's a good, friendly rivalry and I am just glad I eventually came out on top and I don't think I could have handled the banter," he said.
McDonald praised the Well performance despite their defeat in Glasgow and admitted it had been strange playing against them for the first time.
"They are a club that will always have a special place in my heart and I'm glad to see them doing so well," he said.
"They played some good football and will think they were unlucky not to get on the scoresheet."
