The Argentine is Barcelona’s top summer target, but they face competition from Chelsea and Pep Guardiola’s side, according to reports.
Manchester United have also consistently been linked with a move for the San Siro striker, but could be put off by the transfer fee.
Spanish publication Sport (via Sport Witness) claim negotiations between Barcelona and Martinez are progressing well, but the Catalan side are particularly concerned by interest from the Premier League.
And the report claims they face ‘great danger’ from Guardiola’s team.
It is said the 22-year-old is also tempted by a move to Real Madrid, but prefers a switch to Barcelona, should La Liga be his preferred choice.
Martinez has a release clause of €111million, valid in July, and Inter have apparently listened to offers from both Chelsea and Manchester City.
With one of those clubs presenting a ‘totally off-market offer’.
