Manchester United's face the biggest test of their season so far against Barcelona on Wednesday night. 

The La Liga leaders have just touched down in England for the first leg of their Champions League quarter-final tie at Old Trafford.

They'll be looking to take an advantage back to the Camp Nou next week - with dreams of a treble still very much achievable. 

Ole Gunnar Solskjaer may have transformed the Red Devils into genuine contenders since taking over last December. But despite that, it's Barca who come into this match as firm favourites. 

The Blaugrana are in fine form after beating Atletico Madrid in a so-called title decider at the weekend and they also boast one of the most frightening attacks in Europe. 

Lionel Messi is key to that and the mere mention of his name normally has opposition defenders quaking in their boots. 

But apparently, Chris Smalling is made of stronger stuff. Rather than fearing 90 minutes against Messi, the centre-back is actually looking forward to it and wants the Argentine to 'Bring it on'. 

"It's something to relish, this season I've been lucky enough to face Ronaldo, Mbappe, they're all challenges I relish and the players relish," Smalling said, per the Telegraph. 

"I say bring it on."

It takes a brave man to relish a challenge against one of the best in the world, but that's a testament to the confidence Solskjaer has installed in his squad over the last few months. 

The Man United boss will need every single one of his players on top form if they're to get past Barca and reach the semi-finals. 

But after what happened against Paris Saint-Germain last month, anything is possible. Bring it on indeed.
