The Rs forward is delighted with the arrivals of Christopher Samba, Jermaine Jenas and Andros Townsend on deadline day, believing the reinforcements will only aid the team
The Rs signed Christopher Samba and Jermaine Jenas on permanent deals, with Tottenham youngster Andros Townsend joining on loan until the end of the campaign, last Thursday, to add to the £8 million capture of Loic Remy earlier in the window.
All three deadline-day signings featured in the 0-0 draw - their fifth in seven league outings - with Norwich on Saturday and, while the stalemate left QPR six points from safety, Mackie is confident the latest reinforcements are "only going to help the squad".
"It was good for the new lads to get a run out," he told the club’s official website. "They're only going to help the squad.
"Things are certainly looking better for us. Andros is direct and he's willing to take players on; that's what we need. And when you've got someone like Bobby [Zamora] on the pitch, you need deliveries into the box and Andros put a few balls in. He looked lively and he's a youngster so he plays with no fear."
Mackie added that it was vitally important QPR replaced Ryan Nelsen with a player as impressive as Samba, after the veteran left the London side to become manager of MLS side FC Toronto.
"Nellie has been absolutely tremendous for us, as has Clint Hill, so we needed someone to come in and replace Nellie and luckily we have managed to do that with someone of Chris' stature," he said.
"He's a monster, a powerful boy and hopefully he can score a few goals for us as well. If we hang the ball up, not too many people are going to beat him in the air."
