Newspapers are linking Diego Tristan with West Ham. You can see him here:

However, before you get too excited you should read this extract from Wikipedia:

"In total Diego Tristán scored 87 goals in the shirt of Deportivo in 4 seasons. However there have been suggestions that Tristán doesn't live like a professional athlete and doesn't do all he's capable of to reach his best level. Eventually the club ran out of patience with him and he was released on 1 September 2006".

Since then he has failed to impress at Mallorca (0 goals in 13) and Livorno (1 in 20).
