The one player Tottenham really need, but he will cost £30 million

If Tottenham want to make a serious splash this summer, should they aim to beat Manchester United to Luke Shaw?

Tottenham are in the process of attempting to secure their next manager, with Mauro Pochettino the odds on favourite.

The Southampton manager will likely demand his say in transfer business, and that could well involve him casting his eye over key players at the Saints.

Pochettino would be wise to try and delay Manchester United's attempts to sign Luke Shaw while he can, because the England international left-back would be the perfect player to add to his Tottenham side.

Left-back is a serious position of need at Tottenham, with Danny Rose not looking like the answer, and Assou-Ekotto an outcast at this point.

Shaw is already an England international, and signing him could solve the position for the next decade at Spurs.

Beating Manchester United to his signature won't be easy, and Southampton may be reticent to sell to a club who look likely to pinch their manager; but if they money is good then the destination shouldn't really matter - and Pochettino could give Spurs the edge.

The big stumbling block will of course be the money. Tottenham's pot of funds is as yet unclear, but it is not thought to stretch to £100 million like last summer, and investing £30 million on a left-back, no matter how perfect, would limit the club's options for the rest of the transfer window.

Which is why Spurs will have to sell if they are serious about buying, or at least buy first and sell after; and consider putting last season's big signing Erik Lamela on the available list to fetch funds.

Tottenham should of course want the Argentine to succeed, to prove their own point as well as his, but if asked to select who is a safer bet, and needed more so, out of Shaw and he, then the Southampton man may just edge it.

If not Lamela, who could yet thrive under compatriot Pochettino, then there are other options, including the disappointing Roberto Soldado.

If Spurs could fetch half, or three-quarters of the fee required for Shaw from selling one of these, it could just be very worthwhile.
