For David De Gea to even be considering a return to Manchester United in the first place shows just how much love he has for the club especially after the controversial departure from Manchester United. His heart really lies with the club. I don’t see anything bad or wrong with his decision because in the end his happiness is all that matters.
David De Gea must be regarded as the club legend if he decides to return back to the Manchester United team after the way he was treated before his departure, De Gea was a hero for Manchester United during his good form days despite his great saves he wasn't treated well when he was leaving the team I think it's a very bad way of letting a great keeper leave your team after working very hard and making great saves for your team but if he's made up his mind to come and save the team from the embarrassment of Onana then I think the Manchester United team shouldn't just praise his love for the team he needs to be respected cause not all players will do what he's planning to do now.
With the way the club treated David De Gea, I doubt if he'll want to return back, they sent him away without even a farewell and it was so embarrassing to De Gea's personality, he'll only considering going back cause of his love for the club that's if he still loves the club else Manchester United would need to look for another alternative, anyways if they succeed in bringing back De Gea, he'll be an upgrade to Onana cause he's done better than him while he was at the club and he's even doing better than him currently. Anyways it would be very nice to have De Gea back, his good saving abilities would help him perfectly fit into Amorim's strateg.
