What happens when you know the truth is another matter. The point is that until you are aware that your justification for belief is false, you have a justified true belief without knowledge. That's the philosophical problem.Even if your analogy actually happened, I'd still have to accept the fact that it was actually last years match, thus accepting that I was wrong in believing it was this years match. Acceptance must come before true knowledge of facts. The facts will still be presented, but one must accept them before they can confidently say that they know it's true.
The example I gave is one of several variations known as 'Gettier cases' after Edmund Gettier's paper 'Is Justified True Belief Knowledge?' in 1963. The problem is to find a way to 'fix' the definition to deal with them. One attempt suggested that since the justification involved a false belief (e.g. you falsely thought you were viewing the current finals, not the previous year's), knowledge must be true belief where the justification isn't based on false evidence; but you can find Gettier cases that satisfy this constraint and are still not knowledge. Another attempt suggests that you are missing some information or evidence that would falsify the belief (e.g. the information that what you saw was a repeat of last year's match); but again, there are Gettier cases that apply even if there's no missing information or evidence...
And so-on.
