Wilfried Zaha
The Ivory Coast international was heavily linked with a move to Tottenham in the January window, after having seen a failed attempt to sign him in the summer of 2016. However, he ended up staying put at Crystal Palace as they attempt to stave off relegation.
Tottenham have been lacking an out and out wide player in their squad, someone who could stretch the defences with his runs out on the flank and Zaha fits the bill perfectly. The former Manchester United man has been in tremendous form for the Eagles this term, having scored 4 goals and assisted a further 6 strikes already.
With his excellent dribbling abilities and his direct and penetrative running, Zaha would have provided an already strong Tottenham attack, an alternate dimension and could have been a handy signing, but unfortunately for them, nothing materialized.
