The England international was available on a free transfer in the summer.
Whilst the England international has played well all season Tim Sherwood is certainly using him with more gusto.
Delph is no longer playing well, he is playing exceptionally well and Liverpool legend Jamie Carragher cannot believe that one of the European chasers in the Premier League did not snap him up when he was set to be available on a free transfer in the summer.
Carragher, in his most recent Daily Mail column, says Liverpool couldn't deal with him in the recent FA Cup semi-final defeat and suggested other teams were foolish not to make a move for him:
"Earlier this season, Delph was lauded for committing his future to Villa even when their position in the Barclays Premier League was threatened. He signed a four-year deal, which showed his character could never be called into question.
"What can be called into question, however, is the wisdom of some other clubs in the Premier League.
"Delph, do not forget, was set to be out of contract this summer and a number of sides at the top of the table had their chance to sign a young England international for free.
"If Delph does maintain his improvement, inevitably clubs will come looking at him. But if they want him, it will cost.
"For reasons only they know, they let slip a chance to get something good for nothing. Their loss is most certainly Villa’s gain."
The interesting factor in this debate of course, is that Carragher's old team were strongly linked with Delph.
In January it was reported that Liverpool were keen on signing the player, with a fee of £7.5 million mooted by The Mirror. With his contract expiring, he would have been a cheap but excellent buy.
Not long after those reports began to emerge Delph signed a new deal at Aston Villa until 2019, leaving Liverpool, and any other interested parties, looking at a far heftier bill to snap him up.
Carragher seems to think that was a mistake.
