Newcastle United have held exploratory talks with Manchester City over a potential deal for midfielder Nico Gonzalez.The 24-year-old is one of a number of options Newcastle are considering to replace Bruno Guimaraes after his £75million move to Arsenal. They are keen to bring in an experienced midfielder to slot straight in before Sunday’s Premier League opener at home to Liverpool.Gonzalez had been open to a new challenge after failing to cement a regular starting place since last summer’s £50m move from Porto. Nico Gonzalez is keen for first-team football and Newcastle are looking at a moveCity remain keen to add Ayyoub Bouaddi from Lille and Enzo Fernandez from Chelsea but have sold Rodri to Barcelona for £65m, Tijjani Reijnders to Al Qadsiah for £52m and are open to similar offers for Gonzalez.They have signed Elliot Anderson and want to keep Mateo Kovacic but will want to secure more quality for their midfield. Newcastle manager Matthias Jaissle, brought in earlier this month following the exit of Eddie Howe, insisted after Saturday’s 2-1 friendly defeat at home by Bayer Leverkusen that his team will be ready for the new season. ‘We’re not concerned (about Liverpool being so soon),’ he said. ‘We know the reality and we’ll do the best out of the reality. But it’s a huge challenge. You’re all smart enough to see that. But what we can do, it’s pretty simple – we can do our best every day together with the lads we have here.‘The club knows exactly the needs (on transfers). We stick with the plan. There will be some changes, for sure.’
