David plays his first away game for the Hammers on Saturday after making his belated debut last weekend against Tottenham, and Tony says: "David could find himself favourite for the number one spot for the World Cup with the problems England have in that position.
"He is a welcome addition to the team. I think he has a very good goalkeeper and if he has a good two-thirds of the season he could be there."
Looking back on the Spurs defeat last Saturday, which he witnessed, he says: "It wasn't the best of games and I think the worrying thing is that Spurs seemed pretty convincing, and never looked in danger even though they weren't at their best.
"There were players missing but there was not a lot of creativity, although Joe came back and showed a remarkable amount of fitness; he and David James were the only plus points.
"I don't think Shaka will be happy not being in the side because he has had a lot of first team football, but for this season at least he will have to knuckle down and get on with it.
"On the whole he did very well this season, and I don't think he will be sold because you need quality cover.
"Glenn now has Andersson as added cover as well - and he is an experienced keeper at that."
He sympathises with Glenn's plight in the transfer market - the Hammers boss has admitted there is no real money to spend - and says: "He is tight for cash and it just shows you how difficult it is in this league.
"I think the three wins in a week glossed over things a bit - though not in Glenn's eyes - he knows he has a tough job on his hands and he might have to do some wheeling and dealing."
The loaning out of Rigobert Song at least gives Glenn some room to bring in a loan player and Tony adds: "I don't think Rigo quite cracked it at West Ham but I do wish him all the best."
As for the Sunderland game, he says: "We all know that the problems will come from Quinn and Phillips which is one of the most prolific partnerships in the division; it is a bit of an Achilles heel with us in the centre of our defence, dealing with the high balls.
"They have got to cope with it, but you can't disguise the fact that it hasn't been right in that position.
"They will really have to be on their toes - even though they don't always feed off the best of distribution and they make a lot for themselves.
"But we coped with it last season in the FA Cup so you never know; we are on a downer at the moment but the luck might change."
Sunderland have, of course, made enquiries to bring in transfer listed Trevor Sinclair as a replacement for Don Hutchison, and Tony says: "I think Sunderland have missed Don; he gave them something different and it is just a matter of time before he clicks into gear.
"It is a spin up between Sunderland and West Ham who will finish higher; I wouldn't have thought that it is a club Trevor would want to go to, but the game will let them see what they are missing - and he might see that the grass isn't always greener on the other side."
Tony is interested in how West Ham will approach the tactical battle and he says: "Glenn will ponder whether to play a back three or back four; he might go for a spare man picking off the second ball."
Whatever the outcome at the weekend, he is optimistic about the campaign and adds: "It's a long old season and there won't be problems as far as relegation is concerned."
