... What´s that red stuff inside the left engine? Second bird strike in BCN maybe? Anyone got a clue?
After a bird strike on an engine you find the remains
behind the fan blades.
I think the engine pick up some dirt while scraping over the ground.

In reference to the posting of Otterman your speculation can make sense.
But finally we have to wait for the official investigation report.
