Strikers are the focus, as Arsenal continue to be linked with a fair amount of goalscorers in this summer transfer window.

Gonzalo Higuain and Jackson Martinez have been linked, almost confirmed and confirmed depending on what day you read transfer news, and the latest isn't that different.

Higuain is 90 percent certain to join Arsenal, that is according to former Napoli player Jose Alberti.

The Argentina international has been tipped for a move away from the Serie A after Napoli failed to qualify for the Champions League next season. The Premier League trio of Arsenal, Chelsea and Manchester United have all shown an interest, with certain reports earlier this week even suggesting the latter had a transfer inked.

However, Alberti believes Higuain will move to Arsenal this summer. "I'm 90% sure he will go to Arsenal," Alberti was quoted as saying by Metro. "The contract could be a minimum of £3.6million-a-year.

"It's not possible that he will remain at Napoli this year after they missed out on the Champions League."

Another striker reportedly on his way to the Emirates is Jackson Martinez, whose agent confirmed his client will leave FC Porto.

Martinez has a £25 million release clause in his contract, and the agent had said Porto will receive the full amount. It was believed AC Milan were the team to complete a move for Martinez, and not Arsenal, but according to CEO Adriano Galliani, a transfer for Martinez is far from done.

"It's a difficult negotiation," Galliani told La Stampa. "There are a lot of other clubs interested in the player, his wishes will be crucial."

AC Milan don't have Champions League football to offer, which might be a problem for Martinez. Arsenal can offer football in Europe's elite competition, but what is not that clear is if Arsene Wenger will be willing to pay £25 million for a striker who will turn 29 later this year.

Meanwhile, one of the forwards who could be leaving Arsenal is Joel Campbell, with the young Costa Rican linked with the likes of Real Sociedad and Villarreal, the club he was loaned to last season.

Fenerbahce have now joined the race to sign the soon-to-be 23-year-old, with the Metro suggesting Campbell has already given his nod over a move to the Turkish giants.

With Arsenal having quite a few wide attacking options already, Campbell will find it difficult to break through into the first team next season, and his best option will be to play for another club, be that on another loan or on a permanent basis.

Arsenal's other big transfer story this summer has been Petr Cech, and according to the Daily Mirror, Wenger will complete the transfer of the goalkeeper, with the Czech Republic international keen on a move to the Emirates. The report also says Chelsea (read Roman Abramovich) will not stand in Cech's way and will back his decision.

Chelsea will apparently ask for £10 million for the goalkeeper.
