Manchester United's pursuit of Marouane Fellaini will not signal an end to their interest in Barcelona midfielder Cesc Fabregas. United are expected to formally submit a joint bid to Everton for Fellaini and left back Leighton Baines in the coming days. Manager David Moyes has already had a £12million bid for Baines rejected but is ready to test the resolve of Everton chairman Bill Kenwright with an official approach for both players. Moyes has still not ruled out another bid for Fabregas though and will continue to monitor that situation. Fabregas is expected to make his own feelings known at a press conference on Thursday while Fellaini is known to have his heart set on a move to Old Trafford. The Belgian forward 25 is keen to continue his relationship with Moyes the man who brought him to the Barclays Premier League. Meanwhile Moyes has admitted he has found the challenges of his new job difficult to deal with. Moyes who replaced Sir Alex Ferguson at Old Trafford earlier this summer is three days away from United's season opener against Wigan in the Community Shield. Currently dealing with a disgruntled Wayne Rooney and trying to make the first major signing of his time in charge Moyes has plenty on his mind ahead of the new Barclays Premier League season. The United manager said: 'The transition from Everton to United has been difficult at times as I have hard decisions to make. 'Everton are a great club and I was proud to manage them. But I can't deny Manchester United is on another level. Let's be honest it would be a step up from just about any club in the world.' Moyes is considering whether to play Rooney in Rio Ferdinand's testimonial at Old Trafford tomorrow night. The United striker 27 believes he is fit after suffering a shoulder injury at the weekend but Moyes is less sure. The United boss also has to decide whether to release Rooney for next week's England game against Scotland. That will in all likelihood depend on whether Rooney plays any football over the next few days.
