The attacking duo both joined up with the Gers yesterday, and while they can’t take part in tomorrow’s Europa League tie here in Germany, the manager is thrilled to have two more additions to further strengthen his squad.
Speaking at the pre-Bayer Leverkusen press conference, the manager explained: "I am extremely happy with the two players we got in yesterday. I think I made it well-known that we were quite vulnerable with the options we had prior to getting them through the door.
"I am sure they will bring a lot and add a lot to us as a team and a squad. In terms of the club, they have given us good backing and that has always been the same since day one.
"We are on the same page in-terms of the board and myself. The main thing is to try and improve us as an XI and as a squad, and I think getting the names and the calibre of players we did yesterday certainly helps us get closer towards that."
The manager went on to explain what the two players will bring to the club, adding: "They are both different profiles - different sizes if you like in-terms of what you see on the eye.
"Roofe is very sharp and full of energy. He likes to go and press and he is very selfless for the team.

"He has incredible quality around the box and he is very capable of scoring goals in numbers, so, certainly our fans will know more and have seen more of Roofe because of him playing down at Leeds before he moved over to Anderlecht.
"But he has real, strong numbers in-terms of goals to games in his career so far. He is six-foot-two and a half, so comes with power and he is a strong runner.

"So they give us different options. The good thing is they can play together in-terms of how we play and how they fit into our system.
"But I am really excited to work with them both. They are both hungry, they are both looking forward to coming and starting, and they both understand where the club is at and what we are trying to achieve.
"So it is real, big, positive news for Rangers and I am delighted to get them done."
