West Ham co-owner David Sullivan believes Tottenham are the weak link among the Premier League's top six clubs, and the one they have most chance of overhauling.
Speaking to the Sunday Times, Sullivan was asked about the prospects West Ham of building to the point where they themselves can finish in the top six.
He believes it will be difficult given the established squads and heavy spending among the clubs above them, but feels there is one side which they do have a chance of catching.
He said: "It isn’t easy because you go down the list — Chelsea with Roman Abramovich, Manchester United with the best brand in the world, Man City with Abu Dhabi, Arsenal with a great system and having paid off their stadium, Liverpool with commercial income way ahead of ours.
"Then you’ve Tottenham — maybe we can pick Tottenham off. Tottenham are bigger than us at the moment but within striking distance."
West Ham hope to capitalise on their move to London's Olympic Stadium next season, a huge step in building for their future, a ground which Spurs wanted as their own.
Spurs are now pushing ahead with their own stadium, but this will not be ready for another two seasons after the Hammers begin their occupancy in East London.
Despite being close to Spurs over the first half of last season, in and around the top eight, the Hammers sunk, losing form badly, finishing in 12th position, 27 points behind Tottenham.
That in itself is a big number to try and trim down this year. Get close and then Spurs fans may begin taking Sullivan's comments seriously but until then it is unlikely there will be much fear around North London.
