Arsene Wenger has criticised Uefa's drug regulations, saying current rules "basically accept doping".

The Arsenal manager's comments come after Dinamo Zagreb's Arijan Ademi was banned for four years for failing a test after his side's Champions League win over the Gunners in September.

Dinamo have not been disqualified from the competition as regulations state two or more players must test positive before that punishment is considered.

Wenger said the rule was "surprising". He added: "I personally don't agree with the rule.

"You cannot say that they had a doped player but the result stands. That means you basically accept doping."

Wolves' highly-rated 20-year-old Dominic Iorfa has signed a new three-and-a-half-year deal with the midlands club.

The full-back, an England Under-21 international, had been on a contract that expired at the end of the season 

The manager job at Leeds was already a poisoned chalice but owner Massimo Cellino has turned it into a deadly dose of cyanide with his recent use of the vote of confidence.

Dave Hockaday lasted just four days after Cellino said the blame should lie with himself and not the boss.

Uwe Rosler fared a little better, managing 20 days in limbo before he was dismissed by Cellino last month - his decision to welcome the owner's vote of confidence perhaps buying him some more time.

At least his successor Steve Evans seems to not be lacking in confidence, referring to himself in the third person since his unveiling at Elland Road...

Pietersen also said England should regret the decision to drop keeper Jos Buttler from the Test team but had no such remorse about his controversial autobiography.

"I was very annoyed at Jos Buttler's omission from the last Test against Pakistan as I knew he'd turn it around in the ODI series and it makes it hard to pick him for a Test match now," he added.

"I know the South Africans are excited are not having to bowl to Buttler in the first Test now.

"I don't regret the book at all - the people I put away are not involved in cricket or at least in the English set up anymore so there's no problem with anybody."

Former Leeds prop Ryan Bailey will aim to re-ignite his career under his former boss Tony Smith at Warrington. 

The 31-year-old has signed a 12-month deal with the Wolves following his release by Castleford at the end of the 2015 season, with his contract containing a good-behaviour clause.

Smith said: 'It is no secret that Ryan has had a chequered past. However, he is fully aware of the special conditions set out within his contract and the standards expected of all Warrington Wolves players."

Sam Allardyce has received a few votes of confidence over his career but the ones he was given at Newcastle may have been the least believable.

In the run up to Christmas 2007, Big Sam was given repeated backings by owner Mike Ashley and then chairman Chris Mort despite the club's league struggles.

They continued to laugh off reports the manager's time was up as late as 1 January 2008 only for Allardyce to depart just eight days later.

Rumours Big Sam named his Spanish villa 'Casa St James' with his pay-off money were recently debunked by the man himself., external

And there ends the news conference between Tyson Fury and Wladimir Klitschko. The pair shake hands and will battle for the heavyweight title in Germany on Saturday. It should be a barnstorming affair.

Remember, BBC Radio 5 live will have live commentary of the fight on Saturday night..

Wladimir Klitschko: "I am really happy that this fight is taking stage. We will see each other at the workout, the weigh-in and eventually the fight. I want to say thank you to the fans following this fight and it will be a sold-out stadium."

Wladimir Klitschkoresponded to Tyson Fury by saying: "I have faced many fighters that were different. This time, I have a colourful guy who's young and wants the real challenge.

"I heard him say he's nervous, which means he's well-prepared which means he is alert. I'm nervous before every fight, this is fact. I always faced so many challenges."

Tyson Fury: "I hope he has trained hard and I don't want to scare him off. I am going to wind it back in and face fight night. I did not believe this fight was going to happen, but I am coming and I am coming fast. Old guy versus new guy, old champ against new champ."

Tyson Fury is in playful mood ahead of his world heavyweight title fight against Wladimir Klitschko in Germany on Saturday.

"Training is training, same stuff different day, different place," he said. "I was injury free for my whole camp which is cool. We did not leave anything upturned.

"It all crashes down for me when I land in the town and see all the posters, I feel like I am in the fight. I am nervous, I am very anxious, all these people and cameras are making me shy. I am shaking. I hope it is giving Wlad confidence.

"Not really!"

Kevin Pietersen's current main focus may be his cricket camp for underprivileged kids but his thoughts on England's upcoming tour to South Africa are also understandably sought after.

The former England batsman believes the squad "lack experience" and elaborated on his recent criticism of the decision to drop Ian Bell.

"It's only Alastair Cook, Jimmy Anderson and Stuart Broad who have played international cricket out there," he said.

"But so many of us got our predictions wrong for the Ashes and I don't want to predict anything again.

"If Ian Bell had made no runs in the first couple of Tests in South Africa then I would understand him being dropped but when you are embarking on a tour against the best side in the world you need experience."

"We wouldn't have been able to practise on the centre court here until Monday anyway, so it hasn't affected our practices at all."

The vote of confidence. Commonly known as the dreaded vote of confidence.

How often does an under-pressure manager receive the backing of his chairman or club owner only to be sacked or leave 'by mutual consent' shortly after?

It's a well-trodden cliche and one that beleaguered Real Madrid boss Rafael Benitez must now be fearing after receiving the 'full backing' of the most trigger-happy club in football.
