As this is on BoxNation nobody will watch it or give a shit but anyway.
Flanagan (28-0/11 KOs) is the current WBO lightweight "world" champion. He won the vacant title in spectacular fashion when his opponent, Jose Zepeda, busted his shoulder after six minutes and was forced to quit. There's probably around half-a-dozen lightweights in the UK that are more well known than Flanagan. For a "world" champion he's ignored by The Ring and ESPN in their top 10 rankings. SugarJ ranks him no. 10.
Diego Magdaleno (28-1/12 KOs) looks the naturally smaller man. He has the best form though - a SD loss to Roman Martinez and a win, last time out, against Jose A Gonzalez, who has good skills but is a bit of a bottle job. Like Flanagan he is a southpaw, they sort of fight similar, neither are big punchers.
Flanagan - 8/11
Magdaleno - 6/5 (general)
Draw - 22/1
Haven't got a danny. For a degenerate bet - Draw.
