Team News
Newcastle head coach Howe will look to use his full squad over the two matches this weekend, but a strong side is expected to take to the field for the first whistle against Villarreal.
There is no question that the manager will be thinking about his XI for their Premier League opener on August 12, with the fitness of the squad being carefully managed in the two fixtures on Saturday and Sunday.
Elliot Anderson scored a brace against Brighton in the team's last match in the Premier League Summer Series and could retain his spot in central midfield, while new signing Barnes might also keep hold of his attacking role alongside Callum Wilson, with Alexander Isak also potentially coming into the side.
Villarreal, meanwhile, should have a number of their new faces on display in this match, with Sorloth and Brereton Diaz both bidding to feature in the final third of the field.
There should be experience in the midfield in the shape of Etienne Capoue and Dani Parejo, with the latter still at the club despite speculation surrounding his future earlier this summer.
Villarreal have lost some key players this summer in the shape of Nicolas Jackson, Pau Torres and Samuel Chukwueze, so there will be a fresh look to the squad in the upcoming season.
Newcastle United possible starting lineup:
Pope; Trippier, Schar, Botman, Burn; Tonali, Anderson, Joelinton; Isak, Wilson, Barnes
Villarreal possible starting lineup:
Jorgensen; Femenia, Albiol, Foyth, A Moreno; Parejo, D Suarez, Capoue; Diaz, Sorloth, G Moreno
We say: Newcastle United 2-1 Villarreal
With both Newcastle and Villarreal also in action on Saturday, it is difficult to know exactly what to expect from this match. However, both managers are set to name strong sides, and we are backing Newcastle to shade what should be an open and entertaining contest at St James' Park.
