Barcelona last reached the Champions League final a decade ago, with Lionel Messi as their torch-bearer.

Now the Catalan giants rely on another generational talent in Lamine Yamal as their 'X-factor' when they host Inter Milan on Wednesday in a semi-final first leg clash.

At the peak of his powers Messi scored two brilliant goals in the 2015 semi first leg against Bayern Munich on the way to the treble, and while Yamal, 17, is still honing his finishing, he holds the key to the team's potential success this season.
