Liam Bridcutt or Ever Banega, but not both.
Poyet has already added three new players to his squad this January – on loan Fiorentina full-back Marcos Alonso, and Argentinian duo Oscar Ustari and Santiago Vergini.
Now he is closing in on a fourth – another Argentinian, Internacional’s versatile attacker Ignaciio Scocco in a £4m deal.
And he plans more arrivals before the window closes with Bridcutt and Banega firmly on his radar.
