Allan Saint-Maximin is a 'key figure' at Newcastle United who 'brings the best' out of his team-mates on a daily basis.
That is the view of Javier Manquillo, who believes attempting to nullify the maverick who can 'produce something out of nowhere' in training can only improve his own game.
Saint-Maximin has been one of the few bright sparks during the Magpies' poor start to the season, with Steve Bruce's side yet to record their first victory of the campaign.
The number 10 dazzled and scored the equaliser in United's draw against Leeds, and will likely lead the attack against Watford in the expected absence of Callum Wilson.
Saint-Maximin's ability on the pitch and his social media interactions have quickly established himself as a fans' favourite, and Manquillo has revealed how the 24-year-old provides a lift within the dressing room.
He told Sky Sports: "Allan is a great player. He's an important player for us and the club. He provides us as a group with much more besides his ability on the pitch.
"He's a key figure, brings something a little bit different and can produce something out of nowhere. It's great training against him as however good he is, it brings the best out of you.
"You want to be learning from playing against the best players, and certainly Allan falls into this category."
Manquillo has forced his way back into Bruce's plans, scoring on his return at Manchester United before making successive starts for the first time in eight months.
The Spanish defender is keen for this run to continue at Vicarage Road, and believes a continued show of faith from Bruce will only see his confidence rise further.
Manquillo added: "As a sportsman, you thrive off confidence and scoring against Manchester United gave me a boost.
"Clearly, it was great for me to score my first goal for Newcastle but it was a shame for it to have come in defeat. The goal didn't bring us a point so it came with a bitter taste.
"Through playing more games, I feel my confidence growing."
