The 20 biggest deals that could be completed before January transfer window shuts this week

Tottenham, Arsenal and Manchester United are among those set to be busy in the coming days

With less than a week now remaining of the January transfer window, clubs across Europe are scrambling to plug the gaps and clear the deadwood.

In the Premier League, the vast majority of clubs are set to be active. Arsenal are still desperately scouring for a centre-back, with attentions firmly turned towards Flamengo's Pablo Mari after a short-lived pursuit of Shakhtar Donetsk's Mykola Matviyenko.

Meanwhile, Tottenham may well be the busiest club, with Steven Bergwijn, Willian Jose and Krzysztof Piatek all subject to talks. There could be several exits too, with Kyle Walker-Peters, Danny Rose and Victor Wanyama all on the market, as Southampton and Crystal Palace vie for the former.

Manchester United continue to haggle over Bruno Fernandes, with Sporting's evaluation of the Portugal international still far higher than expected, while Chelsea struggle to lure want-away PSG striker Edinson Cavani to west London.

Here are 20 of the biggest transfers that could happen before the window closes on 31 January.
