TORONTO — Toronto FC’s latest debatable decision: Coaching by correspondence.

That is, until the club’s latest head coach retires from European football.

Confused yet?

So are the Reds, in a way.

“We’re not sure when he’ll join us,” club executive Kevin Payne told a packed BMO Field press room Tuesday minutes after introducing Ryan Nelsen as Toronto’s new head coach.

The Queens Park Rangers defender officially replaced Paul Mariner as Toronto’s eighth head coach in seven seasons, sending shockwaves around the league after it was learned TFC’s new bench boss might not join the team until well into the season.
