Brentford have signed American Mike Grella after he agreed a mutual termination of his contract with Leeds United.
The length of the 24-year-old striker's deal at Griffin Park is undisclosed.
Grella, who has represented his country at Under-20 level, signed for Leeds in 2009 but has recently had loan spells at Carlisle United and Swindon Town.
"We are delighted to have Mike on board," said Brentford sporting director Mike Warburton.
"He is a proven goal scorer and we are all looking forward to seeing him perform in a Brentford shirt."
The news of Grella's signing comes following Charlie MacDonald's departure to MK Dons.
