The only Diamond League meet that does a men's 10,000m race before the July/August 'championship window' is Eugene, and I don't think any DL meet does both 5,000m races.
Speaking of which, today's men's 5,000m field isn't the strongest, quelle surprise - though Bernard Lagat (at the age of 41!) might be good competition for Mo as he ran 13:35 (inc. sub-53 last lap) to win at the US Olympic Trials.
