Ferguson has signalled his intent this summer by recruiting Nani, Anderson and Owen Hargreaves, with Carlos Tevez set to bolster the attack when his registration is completed. Although Kieran Richardson, Giuseppe Rossi and Alan Smith have left Old Trafford, there is still plenty for Ferguson to choose from, with Solskjaer hoping to give his boss an attacking option when he recovers from minor knee surgery. The hectic summer is in contrast to a year ago when Ferguson plotted a way to get the better of Chelsea and win back the Premier League title. "Last season he signed just Michael Carrick after not winning the Premier League for three years so the trust and belief he showed in us was very important for us developing as a team," said Solskjaer. "Now he's challenging everyone again by signing a few exciting players. "He's had 20 top internationals every year and to create an environment for everyone to work together is not easy. "He's fantastic at getting the best out of every single one of them. Now we have a squad of almost 30 players so he will need that skill even more. "I can't see any reason why he can't keep everyone happy because he's so good at what he does, challenging us all the time but when you need an arm around your shoulder he's there." Solskjaer has been pleased with his fitness progress and although he is not in full training he believes he is "very close" to a return and is keen to build on scoring 11 goals last season following his long-term knee problems. "It was great being part of it last year after being out through injury," he said. "Football is all about pace and we had that, now with the players we have we'll be quicker." The 34-year-old is hoping to play his part as United challenge on all fronts again, fitting for one of the surviving heroes from the 1999 treble. "Manchester United has always tried to challenge on more than one front; last year we won the league, reached the final of the FA Cup and the semi-finals of the Champions League," he said. "We were capable of challenging last year so I don't see why it's any different. "The Champions League is a different matter - 10 teams can win it." Winning another Champions League is one target in what could be Solskjaer's final year, with reports in his native Norway that he could retire from playing at the end of the coming season. His current deal allows him to develop his coaching experience and Ferguson has talked about the popular striker having a role as an ambassador for the club in the future. "You feel like United's part of your family but so is my Mum and Dad and I've not lived with them for my whole life," said Solskjaer. "But I really enjoy being part of Manchester United."
