How Leeds could improve in three key areas this summer without spending a penny

Leeds United

With few outgoings on the horizon, succeeding in the free transfer market could be paramount for Leeds United

The summer transfer window could be a lot like wearing a straight jacket for whoever's in charge of Leeds United.

Two players are out of contract, three loans are expiring and, if the last seven months are anything to go by, money could be tight - despite the club's apparent top-six aspirations.

There are, however, ways of wriggling free. Here's three quick improvements the Whites could make to their squad.

Tommy Smith for Tom Adeyemi - 

What Leeds could really do with is another centre-back that isn't Giuseppe Bellusci. At the same time, they've an abundance of central midfielders (assuming Liam Bridcutt re-signs).

Adeyemi has started just once since the January arrival of Toumani Diagouraga and a return to parent club Cardiff City is expected.

The spare wages could be put towards Smith - a regular in an Ipswich Town side which has either qualified for or flirted with the Championship play-offs in each of the last three campaigns.

The international colleague of Whites striker Chris Wood is yet to agree a new deal at Portman Road.

Ahmed Elmohamady for Mustapha Carayol

Carayol has hardly set the place alight since joining on loan from Middlesbrough in January and is arguably no better than the Whites already have in Jordan Botaka.

The Championship has several right-wingers out of contract this summer, two of whom, Hal Robson-Kanu and Junior Hoilett, are said to be attracting interest from higher-division clubs at home and abroad.

Elmohamady could be Premier League-bound himself if Hull City go up, but may fancy a new challenge otherwise, with his contract expiring.

The Egyptian's crosses would go some way towards turning Wood into the 20-goal striker Steve Evans insists he can be.

Matty Taylor for Mirco Antenucci

Antenucci is heading back to Italy, it seems, and many Leeds fans would be willing to drive him themselves.

Bristol Rovers' Taylor (not the veteran Burnley midfielder) is set to be of the most sought-after free transfers this summer, having scored 26 goals for the League Two promotion chasers and could be the ideal foil for Wood.

Granted, the Championship would be a big leap for the 26-year-old, who'd never played in the Football League prior to this season, though a certain Leicester striker is proof that a little momentum can take you an awful long way.
