The Magpies trained at the impressive facility at the same time as Burnley, with the two clubs splitting their squads to take part in two concurrent 11 v 11 sessions.

Two evenly-split United line-ups played against experienced and youthful Clarets sides respectively before switching opposition after 45 minutes.

The men in black and white prevailed in each of their respective halves, with a team captained by Jamaal Lascelles beating a youthful Burnley 4-1 over 45 minutes with goals from Joe Willock (2), Elliot Anderson and Miguel Almirón.

Almirón was back on the scoresheet against Burnley's stronger line-up after a short break, rounding off a 2-1 scoreline after Clarets left-back Ian Maatsen had cancelled out Callum Wilson's clinical opener.

Meanwhile, a United XI captained by Dan Burn prevailed 1-0 against an experienced Burnley side led up top by Ashley Barnes and Jay Rodriguez - Allan Saint-Maximin getting the only goal from close range.

After the break, Matt Ritchie and Jacob Murphy were on the scoresheet against a younger-looking Burnley, sending the Magpies into Tuesday's match at Benfica on the back of a clean sweep.
