Arsenal are weighing up a move for Lyon striker Moussa Dembele ahead of their planned overhaul of the squad this summer, Telegraph Sport understands. With uncertainty over the futures of Alexandre Lacazette and Eddie Nketiah, who could both leave the club, Arsenal are exploring possible attacking options to pursue once the transfer window opens. It is understood that they have looked into Dembele’s possible availability this summer, when the Frenchman’s loan spell at Atletico Madrid comes to an end. The Spanish side have an option to buy Dembele for around £30million but it remains to be seen whether they will choose to exercise that option. The former Celtic striker has struggled with fitness issues since moving to Spain in January and is yet to score for Diego Simeone’s side. It is believed that the 24-year-old could be available for around £25m this summer, although Lyon president Jean-Michel Aulas is seen to be one of Europe’s toughest negotiators. Dembele scored 44 goals in his first two seasons in Lyon, including two in last year’s Champions League quarter-final against Manchester City. He was previously prolific at Celtic, scoring 51 goals in 94 appearances for the Scottish club. Telegraph Sport reported last month that Celtic striker Odsonne Edouard is also on Arsenal’s list of potential options this summer. Leicester City are also in the race for Edouard and are seen to be the favourites to sign the 23-year-old this summer, when he enters the final year of his deal in Scotland. Edouard is expected to be available for around £15m to £20m. Arsenal manager Mikel Arteta has made it clear his squad needs revamping this summer and he expects to be backed by the Kroenke family in the transfer market. Speaking on Tuesday morning, Arteta said:"We have already had an incredible amount of changes at the club over the past year or so, more than ever. We are looking to improve and be much closer than where we are at the moment. In order to do that there are certain things that we have to improve. "There are so many things to do because we already have a lot of players on loan and a lot of players with contracts still that we need to sort. It will depend on what happens with a lot of those players and what we are able to recruit to improve the team. That is going to determine where we are." Heaton on verge of Man Utd return Manchester United are close to signing Tom Heaton on a free transfer this summer as a replacement for Sergio Romero. The Aston Villa goalkeeper, 35, will return to the club where he started his career before establishing himself in the Premier League at Burnley. His contract at Villa Park expires next month and he is allowed to talk to other clubs about a pre-contract, with United moving swiftly for a reliable back-up to Dean Henderson and David De Gea. Romero, 34, holds an Italian passport and has interest from Jose Mourinho at Roma among other Serie A clubs. The Argentina international, who played in the World Cup final, worked well with Mourinho during their time together at Old Trafford. Mourinho will look at strengthening his goalkeeper department when he starts work at his new club in the summer, although Romero has sparked interest from other clubs as a free agent. Heaton recovered from a serious knee injury to be back-up to Emi Martinez at Villa this season. Gareth Southgate had him on standby for the last World Cup after being impressed with him around the squad during his England call-ups, which has earned him three caps. United’s fringe players have been on the radar of clubs as they look to pick up talent this summer. Brandon Williams has not played regularly and Brighton are interested in using him as a left wing-back. Southampton have previously inquired about him.
