I'm not saying he can't be seen as an option for the remainder of this season given the right circumstances. This being particularly so with Kagawa, Ando and Nani injured or Welbeck deemed wrong for the game.
However if i didn't feel that Giggs should continue his career next season before today and that for both the sake of the club and his reputation, it would be pretty inconsistent to go back on that because of one good cameo appearance today.
We have young players coming through, there'll be new ones bought, others retire, squad evolve.
Alternatively i suppose i could use today's spark amid the embers to perpetuate a decline.
