Arsenal have made an offer to sign Paris Saint-Germain defender Emmanuel Mbemba on a free transfer. Mbemba has been tracked by several top clubs, including Bayer Leverkusen and Barcelona. The 18-year-old has had a bright campaign with PSG’s Under-19 side, captaining them in the Coupe Gambardella final victory over Montpellier in May. Mbemba has been offered his first professional deal by the French and European champions but he is now expected to leave the club when his youth contract expires this summer. A move to north London would present one problem however as Mbemba is unlikely to immediately qualify for a UK work permit. If they decide to proceed, Arsenal would have to send him on loan to another league until he has secured the required points granting him a permit. While Mbemba would be regarded as a signing for the future, Arsenal are looking to strengthen the squad in four positions this summer at right-back, central midfield, left winger and striker. Julian Alvarez is a dream target up front with talks recently taking place with the Atletico Madrid star’s agent. Junior Kroupi is another option after his excellent season at Bournemouth. In central midfield, West Ham United star Mateus Fernandes is a target but competition for his services is intense with Manchester United, PSG and more recently Real Madrid joining the race for his signature. Aston Villa’s Morgan Rogers has also been identified as a possible summer addition. Arteta has reportedly personally sanctioned a move for the England international but former Villa star Emile Heskey has warned he could find himself down the pecking order in the capital.
