When Barcelona host Atletico Madrid on Saturday, and Sevilla travel to reigning champions Real Madrid the following day, each club will be within four games of potentially becoming Spain's champions.
This is the tightest (six points separate first from fourth), most open (four teams) La Liga title race in living memory. Still more remarkable is that this weekend's potential title decider at Camp Nou will also be a "summit" for two coaches in Barca's Ronald Koeman and Atleti's Diego Simeone. Both either are or should be considered to be fighting to save their job.
