Manchester United vs Barcelona was the most anticipated tie of the Champions League quarter-finals. 

But on Wednesday night, it failed to live up to expectation. Not that Barca will care. 

The La Liga leaders came away with a 1-0 win thanks to an early own-goal from Luke Shaw. 

Lionel Messi had crossed to Luis Suarez at the back post and the Uruguayan's header, which may not have been on-target, deflected off Shaw and past David de Gea. 

It wasn't a pretty finish, but it's one that gives the Blaugrana an important lead to protect at Camp Nou next week. 

Arguably, Barca didn't even deserve the win. They were far from their best, but United were still unable to cause any major problems themselves. 

After going ahead, the visitors took very few attacking risks. But why would they? Messi and co. already had a lead and in the Champions League, that away goal may end up counting double.

There's no question that Barca's early away goal was very important and post-match, Gary Lineker suggested that it might have had a negative effect on the rest of the match. 

In fact, the BT Sport presenter would 'love' to see the away goals rule scrapped in future, to avoid seeing a repeat of games like this. 

"I don't know about you but I'd love to see an experiment for one season where they get rid of the away goal rule," Lineker told his fellow pundits, per the Mirror.   

"I just think home legs, first legs, I just think everyone is a little bit cautious.

"They've got a fear of giving away an away goal or two and, if you get an away goal it's like, 'woah, that's it'." 

Lineker certainly makes an interesting point and his opinion is one shared by many other football fans. 

Away goals always have a huge impact on the Champions League and perhaps it is time for UEFA to refresh the rules - especially if it means we see more exciting first legs.
