Egypt international Mido, 21, the African Young Player of the Year in 2002,
arrives on an 18-month loan spell from Roma.
Mounir, 20, has signed a three-and-a-half-year contract after three seasons at Dutch outfit Excelsior Rotterdam. He is seen as one for the future.
"We never had a worry when our three strikers were fit but if one was injured, for example Fredi Kanoute in the last couple of weeks, we miss a big man upfront," commented Head Coach Martin.
"Now we have four good strikers and it's a good problem whereas before, with Kanoute out, we had a real problem. We only had the one option of Robbie and
Jermain. They are very good players when you can build up in midfield and
create something but in England, you have to play the long ball now and again
and you need a big man.
"Perhaps the media will say it's the end of Keane and Defoe together but I'll say when we're playing well, Keane and Defoe are very good Tottenham players. We just needed to strengthen the squad and we've done that.
"I've been delighted with the quality we've been able to continue to
bring to the club and we look forward to playing some terrific football until the end of the season."
Here's what Martin had to say on the newcomers...
Martin on Mido: "He is a young player, a big man, over six foot tall, very good in the air and a similar player to Kanoute. I think he's a very good asset for the club. He was a young kid at Ajax, top scorer even when Ibrahimovic was playing and Ibrahimovic is at Juventus now. We have him on loan for 18 months and that's a very good thing for the club. He will prove to be a big asset and I know he is looking forward to doing well with us."
Martin on Mounir: "We are looking for talent and he's one of the biggest talents up front in Holland. He's already scored a lot of goals and he's only 20. The English game is different, he knows that. He's here for three and a half years and I hope he does well. He's a very good finisher with a cool head in the box. He won't be playing for the first team in the immediate future but he's a good player and you never know, you've seen what's happened with Ziegler, he came into the first team and hasn't been out. I think he will be a big asset as well."
Martin Jol has welcomed the arrival of strikers Mido and Mounir El Hamdaoui.
