Newcastle United's £18.5m signing Ewen Jaouen has given the green light to the club's next transfer move. The 20-year-old goalkeeper joined the Magpies from Stade Reims last week, and his former coach Christophe Lollichon believes he has the potential to be one of the top 10 goalkeepers in the world. Lollichon, who spent nine years as Chelsea goalkeeper coach, said Jaouen needs time to adapt to the demands of top-flight football. Newcastle are expected to sign an experienced goalkeeper to work alongside Jaouen, with Manchester City's James Trafford a top target. Trafford has had to play second fiddle to Gianluigi Donnarumma at the Etihad Stadium this season and wants regular first-team football. Newcastle are monitoring other options, but Trafford remains their dream signing. The club believes Jaouen can reach his full potential with the right guidance, and Lollichon's comments suggest they are on the right track. Jaouen has impressed at Ligue 2 level for both Dunkerque and Reims, and Newcastle think the £18.5million they paid for him will be worth every penny. The signing of Jaouen is a significant coup for the club, and they will be hoping he can make an immediate impact. With Nick Pope expected to leave the club this summer, the door is open for a new goalkeeper to join Jaouen in the ranks. Newcastle's transfer business is likely to be busy in the coming weeks, and the signing of an experienced goalkeeper will be a top priority. The club's fans will be excited to see Jaouen in action, and they will be hoping he can help the team push for a top 10 spot in the Premier League.
