Yoshimar Yotun - Orlando City - August 12, 2017

With around only 10 matches remaining in the MLS season and playoff races heating up, many of the signings from the summer window which closed last week have already entered the fray.

Last weekend, we saw nine summer acquisitions make their debuts. The results were mixed, but mostly positive. Here's how they fared, followed by the five newcomers we're looking forward to watching in Week 24:

Yoshimar Yotun (Orlando City)

Sabetti: Summer transfer signings hit the ground running across MLS - https://league-mp7static.mlsdigital.net/images/yoshimar_yotun.jpg

With his quality and comfort on the ball, intelligent positioning, and defensive work rate, the Peruvian was Orlando’s best player in the team's 3-1 loss away to the New York Red Bulls, and Red Bull Arena isn’t an easy place to make a good first impression. He did, like the rest of the Lions, fizzle out a bit in the second half. He should have had a goal late in the game, but hit the crossbar instead.

Paul Arriola (D.C. United)

It must have been a bit of a frustrating debut for the US international. And not just because of the loss. D.C. United is a team that still lacks attacking organization and players like Luciano Acosta and Nick DeLeon at times overcomplicate plays. That made it difficult for Arriola to show all of his qualities right away. Still, you can immediately tell from his nifty touches, passes and flicks, and tireless defensive work that D.C. have themselves a strong player.
