Manchester United midfielder Ander Herrera is too creative and dynamic for manager Louis van Gaal, hence why he has struggled in his debut season at Old Trafford.
Furthermore, Mundo Deportivo speculate that Herrera was a signing of Van Gaal's predecessor David Moyes, which may explain why the current United boss has struggled to fit the player into his system this season.
Van Gaal not convinced by Herrera?
Herrera has only made 13 Premier League appearances this season - six of which have been starts - and has often found himself benched for the Red Devils' biggest fixtures.
Fans have been desperate to see the former Athletic Bilbao midfielder in action on a more consistent basis this season, while journalists have regularly asked Van Gaal why the club's big midfield acquisition has seen such little game-time since arriving at Old Trafford.
Van Gaal finally snapped at reporters at the end of January - by which point Herrera had not started a match since December 2 - saying he was fed up of being asked questions about players who weren't playing.
The veteran Dutch coach, in order to accommodate both Radamel Falcao and Robin van Persie in attack, has deployed captain Wayne Rooney in central midfield over recent months - leaving Herrera reduced to the role of substitute.
Herrera gives Van Gaal some food for thought
However, Herrera and Rooney gave Van Gaal some food for thought against Preston North End in the FA Cup on Monday night.
The former scored the all-important equalising goal - his fourth of the season - to keep Manchester United's FA Cup dream alive, while Rooney looked far more effective in his natural position upfront, scoring his first goal since December in the process.
It's true that Moyes put in much of the groundwork to sign Herrera - the Scot came close to bringing him to Old Trafford in the summer of 2013 - but Van Gaal gave the green light for the Red Devils to complete the transfer following his appointment as Moyes' successor.
Herrera can still become a key player for United
Speculation is rife that Manchester United will attempt to sign another central midfielder this summer, while Herrera will fly to Spain early next month to face questioning in court regarding his alleged involvement in a match-fixing scandal.
Despite his struggles this season, there have been signs that Herrera has what it takes to adapt to life at Manchester United.
Van Gaal would be foolish to offload the Spaniard without giving him a fair crack of the whip first.
