With Toronto FC looking to strengthen its roster, primarily in central midfield and striker, manager Ryan Nelsen has some tough decisions ahead.

And, while polite and soft-spoken, the former New Zealand international clearly has no problems wielding a scalpel with his lineup.

From squad selection to choosing his starting 11, Nelsen has one guiding force.

"It's what's going to get us the win," he said after practice Tuesday. "This is a professional environment, it's not about massaging egos or anything like that. My door's always open. As I said it's about getting three points and if people are more interested in worrying about their own spot than Toronto getting three points, this is probably not the place to be.

"But no players in this club are like that. They're all really good guys, they're solid professionals, they understand that everybody gets a fair deal and in the end, it's whatever's best for the team."

Canadian midfielder Matt Stinson was waived Tuesday, the victim of a numbers game and an expected influx of new talent.

Nelsen paid tribute to the 21-year-old, who made 25 appearances in two seasons, calling him a "good professional" and a "fantastic servant."

"Unfortunately there just wasn't enough room as we're moving forward," he said.

The MLS club is inching closer to signing an Argentine player, believed to be 22-year-old forward Maximiliano Urruti of Newell's Old Boys.

Nelsen says the deal is 90 to 95 per cent done, with the rocky financial situation of the Argentine club having slowed the transaction.

Several other new signings are expected, meaning more roster decisions.

"Yes and that's great, that's really good," Nelsen said. "Now with a couple of guys coming back from injury, we're looking deeper now and that's been our problem. We haven't had a very deep squad."

Midfielders Luis Silva and Julio Cesar both practised Tuesday but Nelsen cautioned they had plenty to catch up on due to injury layoffs. Only striker Danny Koevermans (knee) practised away from the main squad.

Toronto (1-2-0) has a bye this week before hosting the Los Angeles Galaxy next week.
