Cole, who spent seven years at Upton Park, was released when his contract expired at the end of last season. 

The 29-year-old scored 59 goals in his time with West Ham, but he struggled for appearances in the previous campaign after the club brought in England forward Andy Carroll on loan. 

Despite only starting 14 games, the former Chelsea player, who has also made the England bench a handful of times, has generated a lot of interest as he is available on a free transfer. 

"There are offers for Carlton from the Premier League, but also interest from Europe and big interest from MLS," Saif told Sky Sports. 

"At this stage we are looking at the pros and cons of each offer professionally and financially as this is a very important next step in Carlton's career and the move has to be right for him. 

"We hope we can make a decision of Carlton's future soon."
