#2 David De Gea

Yes, the Spanish international has conceded the most goals in a single season since he joined United. In the last 10 matches, he has done very little to inspire belief that he is still the best goalkeeper in the world. Howlers against Barcelona, Chelsea, Manchester City and Everton have shown that he is not in the right shape of mind. The second Lionel Messi goal at the Nou Camp was disastrous.
His recent contract demands that involves matching Alexis Sanchez's weekly wages show that De Gea is unsettled. His value is declining by the months so it would be wiser to fetch 60-70 million pounds on him while they still can. Sergio Romero is very much capable of holding down the fort for a season with a suitable back up as United search for a long term replacement. The time is now for the Red Devils to cash in because they stand to lose him for free in the next window.
