Diadora has a rich history in football/soccer with their design of kits.  Many clubs have utilized their services as well as national teams.  Diadora teamed up with Osasuna for this season, and the results were great.

Home

An all red top with a collar is all that is needed to give Osasuna an extremely nice home kit.  The only issue I have with the kit is the large Diadora logos on the sleeves.  I have never been a fan of oversized manufacturer logos.  Aside from that it is a great looking kit.

Away

I have the same issue with the away kit and the over-sized Diadora logos.  The same kit design was utilized for both home and away kits, though the away is a solid white top.  Clean and sharp, except for that over-sized logos on the sleeves.  Takes away from the kit itself in my opinion.
