West Ham co-owner David Sullivan is delighted with the impact of summer arrivals Dimitri Payet and Manuel Lanzini.

The pair have been outstanding for West Ham this season.

"If Payet was 21 he would have been £30m but he is 28," said Sullivan to the Daily Mail. "Some clubs won't sign 28-year-olds. They look for investments.

"We are the opposite. We just want him to deliver for our club. We aren't looking to sell him at a profit.

"Lanzini was a gamble but the total cost of the loan deal was £4m for the season and also allows us to buy him for £10m. I love a deal when you can look at someone before you buy. That gamble has paid off. He is outstanding and he could improve.

"Every signing is a risk. Some players, when they get to a certain level of income and life becomes comfortable, are not the player they were. Foreign players in particular.

"So we try to put them on huge appearance money so that they are driven to play and want to play. But it depends on the individual.

"Payet, for example, is a supreme professional and doesn't need that. When he and Lanzini are both in the team we are very special indeed."
