Time to buy the FarmVille.

That’s the advice a prominent analyst had for CEO Don Mattrick’s tenure atop Zynga.

Mattrick needs to step down from the embattled video game maker to allow some new ideas on a turnaround to be applied, BTIG’s Richard Greenfield said in a report out Friday.

Greenfield’s critique, in a report titled “Zynga Needs a New Leader,” follows Zynga’s report of disappointing fourth quarter results on Thursday.

In the quarter, Zynga reported a 9 percent increase in revenue, to $193 million, and a net loss of 5 cents per share versus a net loss of 3 cents a year earlier.

The company, the maker of the once red-hot “FarmVille” video game, has had a tough time transitioning its games to mobile platforms.

A consensus of analysts expected revenue of $201 million and a break-even three-month period.

As the call for Mattrick’s head reverberated in social media, Zynga stock fell 15.8 percent Friday to close at $2.24 per share.

Not even a plea by Take-Two Interactive CEO Strauss Zelnick to give Mattrick “a little more time” could reverse the retreat of shares that went public in 2011 at $11.

Greenfield questioned Mattrick’s strategy, asking in his report if the CEO used “actual logic or is this just throwing darts?”

Zynga declined to comment.
