The 21-year-old winger published a picture on the site showing him receiving instructions from Cardiff manager Ole Gunnar Solskjaer, accompanied by the caption: "Nothing like someone who believes in you.."

Zaha joined Cardiff on loan last month after making only four appearances for United under Moyes following his close-season switch from Crystal Palace, which could cost up to �15 million ($24.5 million, 18 million euros).

However, despite subsequently deleting the Instagram picture, Zaha declared that he was merely praising Solskjaer, rather than criticising Moyes.

"My picture actually meant ole solskjaer has a lot faith for me to do something for cardiff's current position," Zaha wrote.

"My last Instagram picture was not intended as a dig or indirect at my manager, I have nothing but respect."
