After all, the Red Devils missed an opportunity to meet Fellaini's buy-out clause in July and have failed miserably in their latest bid for both the Belgian midfielder and Baines, according to Sky Sports.
United recently had a joint £28 million bid for both players rejected by Everton. But not only did the Toffees turn down their English rivals, they also described the defending champions' effort as "derisory and insulting." Therefore, it's looking very unlikely that Moyes lands either one of his former players this summer, per Everton's official Twitter account:
While potentially missing out on Baines and Fellaini has to sting for United and their supporters, this isn't a club in danger of missing out on the top four in 2013-14.
Sure, midfield is a weakness for the Red Devils heading into the new season, but as Saturday's 4-1 thrashing of Swansea City proves, the reigning English champions boast more than enough firepower to survive without Baines at the back and Fellaini ruling in midfield.
The reality: Points won't come nearly as easily against the league's top teams, and those challenging matchups are where Moyes will wish his club had made a more enticing bid for the Everton duo.
Manchester City have made a strong effort to improve this summer, spending £100 million on new players, including Stevan Jovetic and Jesus Navas. And their 4-0 destruction of Newcastle in Monday's opener certainly bodes well for their chances of winning the league for the second time in three years.
United aren't foolish, but they are ultra-confident to believe they can fend off their crosstown rivals without having made any notable offseason additions.
It's obvious that Cesc Fabregas was Moyes' top priority coming into this summer, but Fellaini appeared to be the more reachable target of the two, and is younger and more versatile even if he's less of a threat offensively.
Will potentially missing out on Fellaini and Baines come back to haunt Manchester United?
Not to mention Moyes already has a relationship with both Fellaini and Baines having managed the two players at Goodison Park.
Consequently, it's difficult to imagine why Moyes and United would toss such a lame bid at the new boss' former club. Landing one or both wouldn't ensure that the Red Devils win the Premier League and return to the Champions League final this year, but it would be an undeniable improvement for a team just a piece or two away from being the best Europe has to offer.
Everton's latest rejection of United's bid to acquire the talented duo of Baines and Fellaini doesn't derail the Red Devils' championship hopes this season, but it definitely leaves the defending champions vulnerable in midfield, where they will struggle against Europe's top clubs in 2013-14.
