The 13 players Spurs, Chelsea and Fulham could sign for free this year

As the January transfer window draws to a close in the Premier League, attentions are already turning to the summer with a number of big deals touted this month looking more likely to happen come the summer.

One factor that plays a big role in negotiations is how long players have left on their contracts at current clubs. The closer those deals get to ending, the more pressure teams have to cash-in on stars or risk them walking away for free - and that can lead to late deals being struck in January.

For clubs under financial pressure, those free agent deals can work brilliantly.
