It might be another testing time for Henderson and De Gea. Both 'keepers may be under review, and MU will be in the driving seat regarding where either 'keeper plays next season. From all accounts there appears to be support for De Gea within Old Trafford, so Henderson's time at MU (assuming he ends up playing for MU) will be caught in that grey area of indecision.
Personally I wouldn't be unhappy if Henderson returned to the Blades. The overall quality of his game is good, sometimes excellent. Sometimes there's a mistake waiting to happen, but overall he offers more positives than negatives so having him as our number one 'keeper makes a lot of sense. As I wrote earlier, it also enables us to confirm our position as a Prem club (bearing in mind that Henderson has an excellent defence in front of him), so a further season at the Blades harms no one.
It allows Wilder the chance to decide who he wants as this club's number one keeper, and all without that sense of desperation that might mean we sign the 'wrong' choice.
