When will the new FC Dallas signings be able to play?

Since their return to MLS, FC Dallas has played three games, finding themselves with a considerable enemy that has prevented them from winning, the lack of goal. With one game lost and two tied, many fans wonder when their new hires will be able to play. 
Andrés Ricaurte, a midfielder brought from Colombia, will arrive in a week to join the team; and on the other hand, Phelipe Megiolaro, Brazilian goalkeeper, will come in two weeks. This means that the team from two or three weeks will have their new hires. 
FC Dallas needs a change in their game as soon as possible, which their signings can contribute. Many fans hope that the team will find the goal and victory in their next game against Colorado Rapids.
