James Haskell insists his preparations for the Calcutta Cup clash with Scotland have not been affected by the club-versus-country storm.

Haskell, 24, was caught in the middle of a row between England and Stade Francais over whether he should be released for last Saturday's Top 14 match against Toulouse.

Stade president Max Guazzini accused the Rugby Football Union of holding Haskell "hostage", arguing there was no agreement which gave England priority access in a non-Test week.

Haskell confirmed to Press Association Sport last night that his club contract does contain the required international release clauses and he put the situation down to a "misunderstanding" at Stade's end.

When the RBS 6 Nations championship is over, Haskell will return to Paris and hold talks with Stade in the hope of avoiding any future conflict.

In the meantime, the only showdown on Haskell's mind is at Murrayfield on Saturday as England attempt to keep their title bid on track.

"The situation resolved for me as soon as this week started. I have a massive challenge against Scotland and as a professional you can't let anything interfere with that," Haskell said today.

"There was always going to be some question because this is the first Six Nations I have been involved in since going over to France. It was difficult to know what to expect.

"I can't go into details of my contract but I feel that my situation is covered. I made sure everything in my contract is there for me to be released for England.

"Obviously there is some ambiguity over that and I have to go back to Stade and iron things out.

"But I would be letting everyone else down if I allowed it creep into my mindset and Martin Johnson wouldn't tolerate it. As soon as I knew I was staying in England I put it out of my mind.

"My focus has been on my rugby and making sure I am ready for the massive challenge of one of the best back rows we are going to face."

Haskell made no comment while the storm was raging last week but he was aggrieved at the perception that he would have moved to Stade without making the necessary provisions to play for England.

"What I have found difficult to stomach is people questioning whether I have taken the time and detail to make sure this move was the right thing (for England)," said Haskell.

"When you make a massive move like this you have to make sure all your ducks are in a line. It was a very long process and my lawyer sat down for a long period of time to make sure the situation was OK."

Haskell is confident he can smooth the situation over when he returns to Paris after the championship and the row will not affect his relationship with the club.

"Stade have been so supportive of me, especially Max. They have been great about releasing me for various things," said Haskell.

"I have been very honest with Stade Francais, they have been honest with me and a lot of my form is down to them embracing me and allowing me to settle in and find a new life there.

"I am very comfortable there and I want that to continue when I get back."
