Manchester United defender Victor Lindelof knows he faces a massive test against PSG striker Kylian Mbappe.
Lindelof and Eric Bailly were caught out by Mbappe's searing pace when he scored PSG's second goal in a 2-0 win at Old Trafford three weeks ago.
Ahead of the Champions League round 16 second-leg, the Swede said: "I think everyone here knows his qualities.
"He's shown that and he's a world-class player but I'm looking forward to the challenge. He's a good player but you have to be alert and ready for anything."
