Sir Alex Ferguson has cranked up the pressure before the final match of the Premier League season. The Manchester United manager has declared that his team have the experience to win the championship, but while he maintains he is interested solely in his own team's performance away to Wigan Athletic, he has been irritated at reports the Bolton Wanderers squad have begun their post-season break early, celebrating survival achieved by beating Sunderland last weekend.

"All week, people have questioned the integrity of Wigan," Ferguson said. "No one has even mentioned Bolton. Both teams are safe, relaxed and confident. But one can celebrate and the other is all keyed up to play against Manchester United. That difference in attitude amazes me."

Ferguson trusts that his former assistant, Archie Knox, will ensure Bolton are fully prepared for their match at Stamford Bridge. "I worked with Archie Knox for many years at Aberdeen and United. I wish he was playing because he will not enjoy having his players out celebrating and neither will Gary Megson. It is an important game. I am confident in these two guys taking their team to Chelsea."

Manchester United, who lead Chelsea by goal difference at the top of the table, know a victory at the JJB Stadium will clinch their tenth Premier League title. "I said at the start of the season it might go to the wire," Ferguson said. "I am sorry I said that now but we are in the right position. If we win, we have won the league. That is a great incentive for us."

Ferguson will be relying on his senior players, such as Paul Scholes and Ryan Giggs, to make the difference. The Welshman will equal Sir Bobby Charlton's appearance record of 758 should he take the field. "You cannot dismiss having the experience of doing these things," the United manager said. "That is why you last so long. Some players have shared in those experiences and it is important."

The return of Nemanja Vidic will bolster an already mean defence and given Wigan have never taken so much as a point from their neighbours, few expect the home side to present Chelsea with the championship. "The mood has been good," Ferguson said. "We have had an eight-day preparation, which is better than we have had for weeks so any little niggles are all cleared up. I have no fears about their fitness. I have no fears on the confidence side and I have no fears about their form."

And, should United prevail on goal difference, it will not bother Ferguson one bit. "To have a good goal difference gives you an edge on everyone. It is a point I have made for quite a few seasons. You win the league because you are the best team. It doesn't matter how."
