New Wolves loanee Emmanuel Frimpong believes his fighting spirit will see him fit in well at Molineux.
The energetic defensive midfielder completed his move from Arsenal on Saturday on a deal until the end of the season and could make his debut in Monday's Premier League clash at home to Chelsea.
Frimpong has made his breakthrough at the Emirates this season after a cruciate ligament injury held up his progress at the start of the 2010/11 campaign and has already made 14 appearances for the Gunners this term.
The 19-year-old is confident his combative style, which saw him earn a red card on only his second appearance in the league against Liverpool in August, will see him slot in well to a Wolves team battling to stay out of the bottom three.
He said: "It's an opportunity for me to get more games. I'm just coming here to add more quality to the team, hopefully, and I can't wait to get started.
"I'm just happy to be here and excited about my new challenge. I'm a player that likes to fight, that likes to do everything for the team to win.
"I've played quite a few games already this season so it's been a quick step up for me and I've learned a lot during the season and hopefully I can bring something different to the squad here."
The teenager knows he will have to hit the ground running if he is selected for Monday's game, with Chelsea looking to bounce back from Saturday's shock home defeat by Aston Villa.
Frimpong added: "It's a tough game to come into but that's what I'm here for, to play against teams like Chelsea, and if I'm selected I'll be looking forward to the challenge."
Wolves boss McCarthy believes Frimpong will prove a very valuable addition to his line-up.
The Midlanders will also have another new face in the squad, with Iceland international Eggert Jonsson, who can play in midfield or defence, available for the first time after agreeing a permanent move from Hearts last month.
McCarthy told the club's official website: "I'm delighted the deal is done with Emmanuel and he's available for Monday because we need fresh players. We'll be continuing to try and get players in but I'm delighted with the business we have done so far.
"Eggert is an international who has played a lot of games and has more improvement in him and Manny Frimpong is a really great signing for us.
"He's a terrific young player and an exciting prospect. He is an all-action, tough-tackling midfield player who can get about and pass it. I watched him against Manchester City and he got box to box and his career is blossoming.
"He should be a fabulous signing for us. It's good to get people in here for the first games because if you wait until the end of January it's another four or five games gone."
