Many questions were asked of David de Gea when he joined Manchester United in 2011, but the Spaniard's critics are slowly becoming non-existent due to recent performances and now he is rated by many people as one of the best keepers in the world.
De Gea has certainly improved since his arrival at Old Trafford; the 24-year-old's physicality was his weakest point and was the reason why many people said he couldn't make it in the Premier League, however, that part of his game seems to be as strong as any other keeper in the division now.
His presence in the box makes life so much easier for the United defenders, he commands his area so well and a lot of that is surely down to the goalkeeping coaches at the Carrington training ground.
One area the United number one surpasses other goalkeepers in, however, is his shot-stopping. The ex-Atletico Madrid man has cat-like reflexes, as demonstrated in that brilliant save during the match against Chelsea.
Eden Hazard looked certain to score and put the London club 1-0 up, but the United keeper denied the Belgian with a brilliant point-blank save.

In a period of trauma and uncertainty at Manchester United, De Gea has been one of the Red Devils only constants. With the back-four looking shaky, the 24-year-old is often left stranded one-on-one and forced to pull off a fantastic save.
Last season the Spaniard made an incredible 99 saves in the Premier League alone and stopped his side being on the receiving end of an absolute routing on several occasions.
The Spaniard is probably the one of only two definite names on the team-sheet, along with club captain Wayne Rooney. Unfortunately for United fans, due to his brilliant performances and dramatic improvements, will De Gea stay at Old Trafford?
What does the future hold?
There won't be a shortage of clubs after the young Spaniard, footballing behemoths like Real Madrid have been rumoured to be interested in the United keeper and if the European champions place an offer on the table, it may be too good to refuse for De Gea.
After all, a move to Madrid would mean a move back to his home country, however, the fact his previous club comes in the shape of Atletico Madrid, one of Los Blancos biggest rivals, De Gea may have to think twice before he makes a decision if an offer is submitted.
The harsh reality of it is this; is David de Gea too good for Manchester United? Recent performances show he's good enough for any team and if the Red Devils fail to climb their way back into that Champions League position, they may find themselves searching for a new number one.
If the Spaniard decides to stay, he may not add to his silverware collection for a while, but would certainly go down as a fan favourite. There is no doubt the man has big boots to fill, the United fans have had some of the best keepers ever to be seen grace their club, Peter Schmeical and Edwin van der Sar are goalkeeping legends, but De Gea can emulate their outstanding careers if he stays at Old Trafford.
He has plenty of competition in that elite goalkeeper category, Manuel Neuer and Thibuat Courtois have world-class talent, however, the United keeper looks like he will develop more than the aforementioned keepers.
Neuer is at the peak of his career with Bayern Munich and you cannot see him reaching another level before his age starts to creep up on him. Courtois looks like a brilliant all-round keeper, he commands his box superbly and at 22-years-old, he looks set to emulate Chelsea legend Petr Cech at Stamford Bridge.
Nonetheless, at 24-years-old, De Gea has plenty of time to improve further and undeniably become the best number one in the world.
