Gilberto had seven goals in 28 appearances across MLS and Voyagers Cup, albeit with limited minutes. He's a quality player, but apparently had issues with either Defoe or the coach, and may have had language issues, too. He'd probably do much better back in Brazil.
That said, I'm hoping we keep a hold of him somehow. He's not the flashiest player, but he works very, very hard. There was a span of five or six games to start the season where he had chances, but just couldn't bury them. If he were the first striker option for TFC last year, and he was a little bit luckier, 12-15 goals would not have been out of the question. If he were to stick with TFC this year (somehow), I'd peg 15 goals in MLS/VC play as a reasonable return.
