The Montreal Impact currently have CM/LW Ignacio Piatti and F Didier Drogba under contract as Designated Players. Some crafty bookkeeping (possibly through the use of allocation money) made it so that CB Laurent Ciman does not occupy a DP spot. That means that IMFC can add a third DP.
Before we can actually have a conversation about the Impact adding a third Designated Player, we must understand that it may not be possible.
Yes, the Impact only have 2 of 3 DP slots filled. However, it is important to remember that DPs still carry with them a hit to the overall cap ($436,250 regardless of how much the player is paid).
