This is a pretty great effort from these two silky Spaniards
In the past, we've seen Mata take on challenges like taking dizzy penalties or blindfolded free-kicks, and the diminutive Spaniard is back with another video.
And we'll be honest, we're rather impressed by their footwork and juggling skills, even if it did take them a few tries to get the challenge nailed down.
We do wonder though if Manchester United manager Louis van Gaal has seen it and will be ready to give Herrera more game time, with the midfielder only completing three games in the Premier League this season.
United fans will be hoping that Mata and Herrera can show off some of their silky skills when the Red Devils host Slaven Bilic's West Ham United at Old Trafford this weekend.
