Best January Signing?

The lack of spending and reinforcement in January was a big reason we ended up in the situation we did. The justification was that there weren’t any players available who were better than what we already had. But plenty of other teams did good business. Who was the best January signing for you and who would have made the most difference to our squad?

Philippe Coutinho, Aston Villa
Christian Eriksen, Brentford
Bruno Guimaraes, Newcastle
