Exactly! Both Lingard and Petrucci were slaughtered by fans of the loanee clubs after slow starts to their careers (or at least getting raged on because of 'poor' results), Lingard ended up getting 10 minutes here and there getting slammed by the Leicester fans because of his failure to settle and they almost took glee from his loan not getting extended.
Well, Petrucci was taken out of the team for his own good after getting frustrated with himself (and getting a load of shit from fans, including from a certain national radio presenter) but was then was given another chance against Leicester and improved- and smashed in that goal. Lingard has scored some amazing volleys in his time, maybe if Leicester had given him a chance he could have proved them wrong.
Of course there is no obligation, they can pick whatever team they like. To be fair to them, they have solid players in all of Lingard's positions (although maybe not any real depth) so maybe it was just a bad match up, but my point is not to write people off before they have a proper chance.
