Jobi finalised his move to Upton Park on Tuesday evening - following hot on the no less speedy heels of Adam Nowland and Nigel Reo-Coker, who made their debuts in the win over Rotherham - to make it two purchases in two days following the arrival of Bobby Zamora on Monday.
"He is a great prospect and a confident lad; he was another player that really wanted to come to us, which really appealed to me.
"The word is getting out that these young players have a chance, if they come to West Ham, of reaching the goals they want to in their career."
Outlining his qualities, Alan adds:
"He has got fantastic speed and unlocks doors - and really causes defences a problem because he travels with the ball quickly.
"I think he is another player West Ham fans are going to enjoy and we now have three options on the right hand side, when we had none before.
"We have Marlon who is doing it to the best of his ability, bearing in mind he is an out and out striker really - he is doing terrifically well.
"He has now got McAnuff and Sebastien Carole as competition."
North London born Jobi should certainly feel at home at Upton Park for, as well as being the third Dons midfielder to join in the last fortnight, he has also played alongside David Connolly, who joined in the summer of course.
"We couldn't quite get him in at the start but we wanted to be patient and get the right deal that suited us," says Alan, "and we have done what we think are three fantastic deals with Wimbledon - we are very pleased we have got the trio at our place.
"They are a year down the line since David Connolly was at Wimbledon and I think he will see that they have progressed since he last played for them, so it is all good news."
Despite the 'dog eat dog' world football can be, Alan still has time to spare some sympathy for Dons' manager Stuart Murdoch, who has seen his squad decimated while under administration.
Indeed 22 year old Jobi is - make that was - Wimbledon's longest serving player, having signed professional forms for them in July 2000.
"In some ways we have done to them what Premier League clubs have done to us, but that is how it is I'm afraid and Stuart knows that," says Alan.
"He has done an absolutely marvellous job there and will continue to do so.
"He had no control over this and I know that given the right product, he will be a top manager one day."
Alan is looking for his first hat trick of consecutive victories after back to back wins against Wolves and Rotherham against Bryan Robson's men at the weekend, and he concludes:
"Most importantly we have had good results and performances recently and we go to Bradford with a strong bench - when you look at it Saturday I think it is going to be of a standard West Ham should have on the bench, very very good players wanting to play for the team and waiting for their chance."
Meanwhile, Robbie Stockdale has returned to Middlesbrough after his loan spell.
