Fraizer thinks he can save Cats some cash

O'Neill is keen to make quick strides towards strengthening his attack, even though he does not envisage any major deals being announced until after Euro 2012 has finished.

But that will not stop the Sunderland manager from assessing his options in the transfer market, where he has already considered the likes of Norwich City's Grant Holt and Wolves' Steven Fletcher.

Former England striker Emile Heskey - bought by O'Neill during his days at Villa Park - was yesterday released by Aston Villa and is another option available to fill the role as target-man.

But O'Neill, also keeping an eye on defender Carlos Cuellar afte he was also released by Villa yesterday, is adamant he must have two players at least who are capable of scoring more than ten goals next season following a campaign in which Nicklas Bendtner finished as the leading scorer with just eight.

Campbell, whose last of two goals arrived on February 1, feels he has the talent to emerge as one of those, although after an injury-restricted two years at the Stadium of Light he knows his first goal must be to enjoy a full pre-season's fitness programme.

The 24-year-old said: "I would like to think if I played the majority of games I could easily hit double figures, but I just want to concentrate on being fit and putting myself in a position where I can be that player.

"I have not been playing for the last couple of seasons so it would be hard to put that kind of tag on me [a prolific striker]. For me it is just a case of concentrating on my football.

"And if I score a few goals then I score a few goals. It is something to aim for. If I have a good pre-season and get as fit as everybody else then it helps you a lot.

"During the season the training is not as intense as it is at the beginning and you don't really get that good solid base, but hopefully this time it will be different for me."

There is likely to be a number of changes at Sunderland this summer. Following the departure of Craig Gordon, the first team squad could now see the likes of Ahmed Elmohamady and Kieran Richardson being sold. Campbell himself was linked with a move to Fulham over the weekend.

But the former Manchester United forward, who hopes to play some part in the Olympics for Team GB after his omission from the Euro 2012 squad selected by Roy Hodgson, is keen to focus on staying fit and building up his confidence.

After returning from two serious cruciate ligament knee injuries with two goals in his first two matches he was handed his first England cap in the defeat to Holland on February 29.

"Thank God that's (2011-12 season) over!" said Campbell. "Obviously it was disappointing to be injured all that time, but having said that it did make it even more special when I came back, scored the goal and got my England cap.

"It is mixed emotions, really. There have been some good bits and some rubbish bits, but hopefully I can continue with the good and leave all the other stuff behind. It has been a strange one, but I will be back next season."

Despite the disappointments, Campbell will cherish the memory of his stunning striker against Norwich on February 1. Not only was it a special finish, it was also his first in the Premier League since April 2010.

"When I was injured at the start of the season I would have been delighted just to come back and to have played a couple of games. It was a bonus to be involved and score in the games that I have done," he said.

"My main focus was just to stay fit until the end of the season and just get a good start with the rest of the lads - get as fit as everyone else and compete from there.

"The goal against Norwich was alright (smiles), and you don't score many like that very often. When something like that comes off, obviously it is one you will never forget.

"There have been some great goals this season, though, and I am just happy with my goal without spending time worrying about other people's."
