After a lengthy discussion with manager Rafa Benitez, the Algeria global is eager to be the Magpies' new leading man, potentially starting with his club debut in their home game against Manchester United on Sunday - but he must first overcome a thigh injury.
The full-back's future at Old Trafford has at times been unclear, with Shaw often falling out of favour with the Portuguese.
Shaw has cemented his place as a semi-starter with the left back position being rotated alongside the in-form Ashley Young.
United's record scorer Wayne Rooney, appearing as a television pundit, suggested Mourinho is not playing Pogba in the right role.
Pogba has scored three goals in 16 Premier League appearances this season, contributing nine assists, and Mourinho rejected suggestions the France global should be offering more to the team due to his EUR105million transfer fee.
"With Luke it is not about changing my mind, it's just the evolution or no evolution of his potential", Mourinho added. "It's just about that". And he made a big effort.
Last month's defeat to Tottenham is the only blemish on United's 2018 to date, with no goals conceded in their other six league and cup games so far this year, all of which have been won. Also Huddersfield but only once.
"(Rafa) Benitez knows how to get points so I think it is going to be hard". I like to go there and like the feeling of going to Mr Robson's home. I like the Geordies, I like to go there. "But [Rafael] Benitez knows how to get points, so I think it's going to be hard". I think they are a good team and I think they have a very good transfer window with Kenedy and [Islam] Slimani, two players I know well who can improve their team. "Rafa Benitez is one of the best managers at setting teams up not to lose games, and with players like Jamaal Lascelles at set-plays, you never know". They are a big club. "But I have seen Burnley, West Ham, Stoke, Leicester - a lot of teams playing defensive against Manchester City", he told the assembled press at his weekly press conference.
Asked if he would be scared to adopt a similar approach when Jose Mourinho's men head for Tyneside on Sunday, Benitez replied: "What would I be scared of?"
