It was 2 years ago and I have never seen a more exciting game involving Chelsea then this one in my 10 years of supporting them. It was the 2nd leg involving Barcelona at Stamford Bridge. The build up was intense but the game was bewildering.
Another good game I remember was an FA cup game between Liverpool and Luton town. It took me a long time to find a good compilation in the end I found a rubbish one but it shows the goals.
Other games I liked in recent years are too obvious and everyone will remember them so I won't post them.
The best game I have ever watched since Jose joined
