Many fans had thought rumours of interest from the likes of the Rossoneri was simply agent talk or Sampdoria trying to squeeze more money out of a deal that could cost the Hammers as much as €8.5 million, according to co-owner David Sullivan's son Jack on Twitter.

However, Gonzalez has now revealed the interest was very real but despite AC Milan's stature and size, he feels his client's move to West Ham was the right step for his career.
“(This is) An important step for his career: everyone knows the Serie A but I think the Premier League is the perfect league for his style of play, for the characteristics he has,” he told Tuttomercatoweb.
“Were AC Milan close to signing him? No, it’s true we spoke to the Rossoneri but West Ham were much more decisive."
“They showed they have a growing project, it is a very important decision for him."
Obiang impressed as an ever present for Serie A side Sampdoria last season and West Ham co-owner David Sullivan has backed the club's newest recruit to become a 'real superstar' during an interview with the club's official website.
The 23-year-old started his career in his home country with Atletico Madrid before leaving for Sampdoria in 2008 where he has risen through the Italian side's youth ranks into the first team.
He has played 132 times for the Italians scoring four goals, three of which came last season as he really emerged as a fans' favourite.
