It's that time of year again. The January transfer window is open for business and all 20 Premier League sides are looking to strengthen. As with every season motives are different. Some clubs are trying to stave off relegation, others advance their lot by pushing for Europe. The title race and four Champions League spot remain as wide open as they have in years at the top. Some managers are known to dislike the winter window, but love it or hate it only the brave or foolish ignore it. Certain teams desperately require strengthening to realize their ambitions and others need to have a quiet month, ensuring they hang on to their prized assets. Players seeking moves may have extra motivation to do so this January as we are now in a World Cup year. Competition to make the plane to Brazil will be cut-throat for many of the 32 countries involved in the greatest sporting show on earth. National coaches want their players getting regular football in the run-up to the World Cup. That can cause crazy winter gambles by outsiders to force their way back into the fold in time for June. All these considerations have been weighed up by the WhatCulture sports team. So, for your delectation we have gone through all 20 English top flight teams, assessed what they need, who they have been linked with and who we would like see join them. We proceed alphabetically, so click next to start with Arsenal.
