Might be unpopular, but if Inter really needs to sell, I'd perhaps look at Lukaku. Yes he's clumsy but we're crying out for a focal point in attack. He's quick, his hold-up play is really solid and his passing is actually really good at times. He's got a great connection with KDB and has only missed double-digit league goals in 2011/12 when he couldn't get in the Chelsea team. He plays in a 2 which could complement Jesus (who's pretty similar to Martinez) and he gets a decent amount of assists. Also he'd add a lot to our presence in the box, and between him & Dias, could score a lot from corners. He's lost a lot of weight since they put him on a new diet (I read he had a condition the medical team picked up on weeks after signing for Inter and he lost 1.5 stone in 2 weeks).
He's got a good scoring rate in the Premier League despite playing in some shit teams (West Brom, Everton, United) and very defensive teams (United, Inter under Conte). Plus, it'd boil the piss of the Rags if we won the league with him, kind of like Tevez.
