Ignacio Piatti came off the bench to make his long-awaited return from injury as the Montreal Impact were held to a 0-0 draw against the New England Revolution on Saturday afternoon.

Evan Bush made four saves for his sixth clean sheet for the Impact (6-5-3), who have one win in their last four games.

Goalkeeper Matt Turner earned a one-save clean sheet for the Revolution (3-8-3) in new coach Bruce Arena's first match in charge. It was New England's second shutout of the year.

After a first half largely controlled by the Impact, the 15,559 in attendance at Saputo Stadium began chanting Piatti's name as soon as he began warming up in the 55th minute. The Argentine came into the game 11 minutes later to a rousing ovation.

The Impact's star midfielder had not played since March 16, missing the last 10 games with knee and calf injuries. Montreal went 4-4-2 in Piatti's absence.

But Piatti could not make the difference, and both teams squandered a handful of chances to settle for the draw.
