Andre Villas-Boas is being promised more cash from Daniel Levy to chase a new striker. And that will bring Jermain Defoe’s future back into doubt, as MLS clubs queue up to offer him an escape route, the Sunday People reports. Despite a shopping spree of almost £100million in the summer, Spurs officials are willing to back Villas-Boas again to boost their hopes of a title push. And FC Porto striker Jackson Martinez is one target AVB continues to show serious interest in. The 27-year-old Colombian has been offered a new contract at Porto, although a host of clubs including Borussia Dortmund, Napoli and Arsenal are also interested.
