Dos Santos, Guardado 8/10 as Mexico keeps rolling

That's now four wins in four games for new Mexico manager Gerardo "Tata" Martino. Following Sunday night's 3-2 victory over Ecuador, the Argentine has remained undefeated in the lead up to this summer's 2019 Gold Cup.

Ahead of the CONCACAF tournament, here are some takeaways and player ratings from the most recent El Tri result.

Positives

It's all about that chemistry. For a team that has had to deal with absences and injury problems, Mexico once again looked like a highly organized and cohesive unit against Ecuador. Throughout the match, Martino's men were efficient with their passing and did an excellent job of rapidly moving the ball up the pitch.

Scoring multiple goals against South American opposition -- for a fourth game in a row -- is also another sign of progress under the new manager.

Negatives

Injuries have once again become a talking point. Hector Moreno was seen lying on the floor in the first half and was later substituted out in the 35th minute. Early reports have put his place in the Gold Cup up in the air.

Mexico's overlooked problems in the backline should be brought up as well. Despite the noteworthy success in the attack, El Tri has also allowed six goals in the last four friendlies.

Manager rating (out of 10)

8 -- In a short amount of time, Tata has immediately found a way to arrange his roster into a well-oiled and attack-minded machine. On Sunday, the midfield excelled in a three-man formation and supported the frontline that had plenty of service going forward. The only issue is that Mexico now looks vulnerable through counters, which is something that might hurt the squad in the Gold Cup.

Player ratings (1-10, with 10 the best. Players introduced after 70 minutes get no rating)

GK Guillermo Ochoa, 6 -- Although neither of the goals were his fault, Ochoa didn't do much to stand out between the sticks. An average evening for the veteran who will likely remain the starting option in the Gold Cup.

DF Luis Rodriguez, 7 -- "Chaka" went from an underwhelming player to a pivotal figure during the final stages of the win. After creating mistakes and allowing Ecuador to score their second goal, the right-back compensated with a game-winner in the 2nd half and an active performance in the final 15 minutes.

DF Cesar Montes, 6 -- A fairly standard game from the 22-year-old. A deflected header into his own net was unfortunately the highlight for the central defender that wasn't as assertive as Carlos Salcedo or Moreno.

DF Hector Moreno, 7 -- The veteran was a solid presence in the backline until his injury. After suffering a knock, Moreno was brought off the field in the 35th minute.

DF Jorge Sanchez, 5 -- Unfortunately, Sanchez was one of the most quiet players on the pitch. The left-back will expectedly be a backup option for Jesus Gallardo this summer.

MF Jonathan dos Santos, 8 -- No player on the field worked harder than Dos Santos against Ecuador. The LA Galaxy player constantly pressured the ball, dashed around the field and scored the first goal of the game off an accurate shot from distance.

MF Andres Guardado, 8 -- If the Mexican national team was a symphony, Guardado would surely be the conductor. Sitting in the heart of the XI, the captain dished out instructions while constantly making himself available for passes. After eventually moving into a more advanced role, Guardado became a key playmaker for Mexico.

MF Luis Montes, 7 -- Lost in the shadow of the midfield work of Dos Santos and Guardado, Montes stole the spotlight away through his golazo in the 63rd minute. At 33 years of age, "Chapito" is still capable of being a vital component for Mexico.
