Arsenal boss Mikel Arteta is looking forward to locking horns with Rob Edwards tonight at Luton Town.
The pair originally did their coaching badges together.
Arteta said: "He's a great coach and a really special person as well. You can tell the way he coaches his team and the way his team behaves and I'm very happy for him and what he's doing. We've stayed in touch because he was at Watford not long ago so we've been pretty close.
"I think they are a really good team and probably the table does not reflect what they have done in many games.
"The way they have lost games or drew games as well in five minutes during the final stages of games. As I say, it probably doesn't reflect that, but it's a difficult game, that's for sure."
On the Kenilworth Road atmosphere, he added: "They know. We have already warned them, they know what to expect. They know about the atmosphere and they know about the access. They know everything, and especially they have to know about the team that they have to face tomorrow and the difficulties we are going to have to play against them, and as well what the opportunities are for us to win the game."
