Matias X del Azar: The big match tonight has to be the Bayern Porto clash, going to be an absolute cracker. No nonsense from Barca with both Mascherano and Busquets. Don't think three goals is ever going to be on the cards tonight.
Gregory Bortkiewicz: With Bayern's injury list and Porto's great form, it really is a coin toss for who goes through. I fancy Porto.

Evening all. It's set up rather nicely in Germany, isn't it? The rumbles won't just be heard in Munich if Porto complete the job tonight. They will be seismic and felt all over Europe. This is a big game for Pep and the boys. Failure is not an option.

It's not just the fact Julen Lopetegui can balance a football on two fingers... it's the fact he's steered Porto to a 3-1 first-leg lead against the mighty Bayern Munich in the quarter-finals of the Champions League. They can't, can they? They won't, will they?
The next Jose?published at 18:46 British Summer Time 21 April 2015
26 May 2004... football has never been the same since.
Why? Well, that was the day Jose Mourinho shocked Europe by taking unfancied Porto all the way to the Champions League final. And winning it.
Eleven years on, we're still being entertained off the pitch by The Special One, and continue to marvel at his achievements on the pitch.
But is there a new sheriff in town? Ladies and gentleman, I give you Julen Lopetegui.
