The 24-year-old only made the move to the Hammers from Sassuolo last summer, but he found it difficult during his first campaign at London Stadium, only managing three Premier League goals.
Scamacca's future has been the subject of much speculation in recent weeks, and according to Calciomercato, an agreement with Roma has now been reached.
The report claims that the Italian outfit are preparing to sign the forward on loan for £4m, while there will be a £19m option to buy if he plays a certain number of matches for the club next season and helps them to qualify for the Champions League.
The Italy international, who netted eight times in all competitions for West Ham last season, has another four years left to run on his contract at London Stadium.
Meanwhile, Besiktas have reportedly expressed an interest in signing Everton attacker Demarai Gray this summer.
The 27-year-old's future is currently the subject of much speculation, with the likes of West Ham and Crystal Palace being linked with his services.
According to the Daily Mail, Besiktas have now made an enquiry, with the club keen to bring him to Turkey during this summer's transfer window.
The report claims that Everton are keen to keep hold of Gray, but he only has one year left to run on his contract and is considering his options.
The attacker arrived at Goodison Park from Bayer Leverkusen in the summer of 2021, and he has represented the Merseyside outfit on 75 occasions, scoring 12 goals and registering six assists in the process.
Elsewhere, Sheffield United are allegedly closing in on a deal for central defender Axel Tuanzebe.
The 25-year-old is available on a free transfer this summer following his release from Manchester United.
Tuanzebe appears to be heading straight back to the Premier League, though, with Sheffield United thought to be nearing a deal for the centre-back.
According to journalist Alan Nixon, discussions between the two parties are advanced, with Tuanzebe set to undergo a medical with the newly-promoted outfit before his arrival is confirmed.
The former England Under-21s international spent the second half of last season on loan at Stoke City, while he has also previously had short-term spells at Aston Villa and Napoli.
Moving down to the Championship, Leeds United have reportedly made the decision to sell goalkeeper Illan Meslier during this summer's transfer window.
The 23-year-old's future has been the subject of much speculation during the recent market, and according to Football Insider, the Whites are prepared to let him leave.
The report claims that Leeds want between £20m and £25m for the stopper, which is a drop on the £40m that they had allegedly been demanding in the early stages of the window.
Chelsea, Tottenham Hotspur and Man United are among the clubs to have previously been linked with the Frenchman, who has represented the Whites on 126 occasions in all competitions.
