Lukas Podolski wants to return to Arsenal when his loan expires at Inter Milan, according to manager Roberto Mancini.
Neil Redfearn has taken heart from Leeds' claims that their young first-team players will not be sold in the summer.
The 25-year-old striker has attracted interest from several of Europe's top clubs with his performances for current club Celta Vigo - and Michael Laudrup was rumoured to be lining up a move.
But his agent, Felix Gende, said: "It's clear that there are a lot of clubs following Iago because of the season he is having, but right now it is impossible that he leaves for another club in January.
"He is focused on helping his team retain their Primera Division status. Come June, when there are a lot more transfers, God will say what happens with his future."
Aspas' 23 goals last season inspired Celta to promotion to the Primera Liga, and he has netted six times this season in Spain's top flight.
