Good evening and welcome to LIVE coverage of Barcelona against PSV Eindhoven on the opening night of this season's Champions League.

FT: Barcelona 4-0 PSV. An eighth Champions League hat-trick for that man Messi sees Barca off to a fine start in this season's Champions League. It was laboured in the beginning, sublime by the end. The goals were of the highest calibre, with Dembele's arguably the pick of the bunch. Tottenham beware. Thanks for joining us. Goodbye.

Elsewhere in the group...

Lozano whips a cross into the middle, but Barca get it clear at the second attempt. That's them done.

Indeed.

Five added minutes here...

So, so easy. Great build-up from Barca, Suarez steers the ball through for Messi and, on his supposed weaker right foot, he rifles the ball into the bottom corner for another Champions League treble.

GOOOOOOAAAAAALLLLLL!!!! Barcelona 4-0 PSV. Hat-trick number 42 for Messi to complete the rout.

Final change for Barcelona, with Arturo Vidal coming on for Rakitic.

Erick Gutierrez replaces Rosario for PSV, and immediately has the ball in the net, but it is ruled out for offside.

Two changes for Barca. Clement Lenglet and Arthur replace Dembele and Coutinho.

RED CARD! Not all good news for Barcelona as Umtiti blocks off Lozano to earn himself a second yellow card and his marching orders. He will now miss the trip to Wembley to take on Tottenham.

Wonderful pass from Rakitic over the top for Messi, who took it on the half volley - the result was glorious.

GOOOOOAAAAALLLLL! Barcelona 3-0 PSV. Touche Lionel, touche. Two for Messi, three for Barcelona, game over.

Anything you can do, Lionel, Ousmane can do better. As good a individual goal as you will see from the 21-year-old. He showed wonderful skill to get away from his man, before curling a strike into the bottom corner.

GOOOOOOOALLLLLLL! Barcelona 2-0 PSV. I spoke to soon, and what a goal it was from Dembele!

Barca have slowed the pace of their play right down now, seemingly content with a 1-0 win.

Early kick offs are not putting the masses off it seems...

PSV are not out of this. They are pressing and pressing here. All it takes it one mistake...

WOODWORK! Incredible improvisation from Suarez and he goes to chip Zoet, beats the PSV goalkeeper, but sees his effort hit the crossbar and fly over the top.

Nicolas Isimat-Mirin is on for PSV in place of Viergever.
