Former West Ham and Swansea forwards are starring for Villarreal.
Calleri had a poor season at West Ham on loan from Boca Juniors in 2016/17 where he scored only one goal in 18 games.
Borja Baston had a nearly identically woeful record the same season, scoring one time for Swansea City in 20 games. The difference was the Swans paid £15.5m for his services.
Both players are now proving unlikely heroes for Spanish side Alaves.
The unfancied side sit in second place in the La Liga, table.
They are just one point behind Barcelona and are six points ahead of ninth placed Real Madrid.
10 games in the season a Champions League place chase is a remarkable possibility.
Yesterday Calleri and Baston both scored as Alaves came from behind to beat Villarreal 2-1.
Calleri now has three goals for the season with Baston now netting twice.
Last season Alaves finished in 14th place. This season they are enjoying a remarkable turnaround and the two men scoring the goals are just as surprising.
