Mauro Diaz returned to the FC Dallas line-up last weekend by making an immediate impact.

The Argentine midfielder had missed five weeks of action with a leg injury before netting the opening goal in the 1-1 draw with Colorado Rapids.

It was Diaz's fourth appearance of the season, and first since March 21, which comes after an injury-interrupted 2014 where he managed just 17 run-outs following his transfer from River Plate.

Of the Diaz performance, Dallas boss Oscar Pareja was quick to praise his classy player who he feels will soon rediscover his very best form.

"It's natural with a player that didn't have too much continuity last year to retake his full level," Pareja told MLSsoccer.com.

"It takes games, especially when we wanted to work on his strengthening and his balance to avoid future injuries. So it's a process for sure, but I do really see all things coming back.

"He brings calmness," Pareja added. "Like I said before, he turns the lights on in the last third of the field especially. That's his ability. He does that job well. So it's good to have someone who can glue us in the middle, and at the same time have that final pass and decision right.

"We are happy to see a player who is important for the group, who has different characteristics getting back to that level.

"It'll take a few games, but we're in a good direction."
