Romelu Lukaku "will want revenge" against Manchester United, according to Dimitar Berbatov, who says the Inter striker "would love" to knock the Red Devils out of Europe.
After two frustrating years at Old Trafford, Lukaku completed a £74 million ($97m) move to Inter last summer to join up with ex-Chelsea boss Antonio Conte at San Siro.
Despite scoring 42 goals in 96 games, the Belgian was the subject of intense criticism during his time with United, as his first touch and quality in the final third of the pitch were regularly called into question.
