FC Dallas' latest acquisition is finally official, so what can you expect from Harold Santiago Mosquera?

The Colombian has been brought in primarily as a left winger. At Millonarios, Santi spent more time on the right side and made a name for himself as a strong goalscorer in the U20s on either flank or as a 10/second striker. Michael Barrios was known to switch wings with Fabian Castillo and had also played as a 10/second striker in Colombia. There could even be a few three-way switches when Paxton Pomykal sees time in the first team as a 10 who can play on the wings.

The Castillo-Diaz-Barrios threat was the unpredictability that meant defenders couldn't sleep on any of the three. With Roland Lamah not fitting in with the FC Dallas style of play, teams could focus on Barrios and Diaz. While this did leave Lamah unmarked in the box on occasion, it did have the effect of a significant downturn in production from both wings.

Mosquera, who turned 23 just last week, has pace. Not quite Fabian Castillo, but Mosquera can turn on the jets when he is required to. Santi's turn of pace is perhaps what is most impressive. He will turn defenders inside out on the run, but he has great positional awareness in creating space.

Where his acceleration is a far greater attribute than his top speed, you will see him slow things down, and take a couple of touches before leaving a marker completely flat footed as shown above. He will use a step over to create a yard to get a shot or cross away, and a good number of his eight goals and eleven assists last year came that way.

One facet of Mosquera's game that suits the style Oscar Pareja prefers is his tendency to cut inside. FC Dallas are not a team that will succeed with a crossing game and Santi will cut in from both wings to create opportunities at the edge of the 18 rather than the byline. Look for him to involve Mauro Diaz when Diaz lurks around the top of the D looking to play Maxi Urruti or Crisitan Colman in. Mosquera isn't afraid to shoot off either foot, although his right is clearly his preferred option. You will see him drill shots from his laces with his left, while he has more control on his right instep for those curling efforts from wider out.

Defensively, he tackles like a typical forward, but he will track back and pressure his opposing number. If FC Dallas does make use of a back three, there will be times he covers for Nedyalkov and aims to contain a runner close to the touchline allowing Nedyalkov and the defensive midfielders time to recover. That was always one part of Fabian Castillo's game that could have been improved whenever the left back overlapped.

Overall FC Dallas is paying a reported $2m for a 23-year-old that seamlessly transitioned from youth to senior football, can get among the goals and create chances, and most importantly provide a presence on the left that has been missing.

This looks like a Carlos Gruezo type of investment where the Hunts outlay what is still a significant amount for them, with a strong upside. It should be remembered that Santiago Mosquera only has one full season and 54 games under his belt, but it looks like a promising signing in an ideal environment for a young South American player.
