Live to fight another day. That was likely what Barcelona coach Ronald Koeman was thinking around the hour mark on Tuesday when, 2-0 down at home and on the way to defeat against Bayern Munich, he hooked veterans Sergio Busquets and Sergi Roberto and did the football equivalent of a bedraggled basketball coach emptying his bench.
On came Gavi and Yusuf Demir, two guys who are a combined 35 years old, have played a total of 47 first-team minutes and probably would not be recognised by many Barca fans if they showed up at the front door to deliver a pizza.
