No wonder I couldn't find anyone immediately identifiable...
What to do, when both teams have uniforms the same colour? Many of the IPL teams seem to be wearing blue or something very close to blue. As if that weren't enough, I just tune into this La Liga match and there they are. It took me a few minutes to figure out that the ones in green were FCB in their 'Away' coulours. Levante's colours got me confused :(
This helped too, especially this : "Both sets of players are now on the pitch as they go through the usual formal pleasantries. Levante are in their red and blue striped shirts with blue shorts while Barca wear a ghastly green kit."
