Marcos Senesi is one of the best central defenders in the Eredivisie and Roma are aware of that. Therefore, they have focussed on him as a possible replacement for Smalling in case he ends up leaving for the Premier League. At the moment, leaks indicate they have already turned down an offer from Everton.
In any case, 'Il Messaggero' reports that the club from the Italian capital are interested in the Argentinian defender. They have to negotiate with Feyenoord as his contract runs until 2023. His market value is around 15 million euros.
The former San Lorenzo's player good campaign in the 2020-21 season means that he is a good reinforcement even if he does not go to Roma. He played in more matches and he was the protagonist in many of them. The key will be what Jose Mourinho thinks of both of them. He will decide how he wants his team to be.
Age is another factor to bear in mind. Marcos Senesi is 24 while Smalling is 31. Looking towards the future, the club may recommend the Portuguese coach goes for the former because of his youth.
