The Hoops completed deals for Chris Samba, Jermaine Jenas and Andros Townsend on deadline day after Loïc Rémy signed earlier in the January transfer window.
“It was good for the new lads to get a run out, they’re only going to help the squad. Things are certainly looking better for us,” Mackie told QPR’s website.
“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 that QPR replaced Ryan Nelsen, who has become Toronto’s new manager, and the Scotland international was pleased to see the Hoops complete a deal for Samba.
“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’s stature,” said Mackie.
“He’s a monster, a powerful boy and hopefully he can score a few goals for us as well. If we can hang the ball up not too many people are going to beat him in the air.”
