Tottenham Hotspur may be regretting their decision to allow Giovani Dos Santos go now that they are facing such problems in forward positions.
The Mexican signed for Spurs from Barcelona back in 2008 and spent four years at White Hart Lane, but was allowed to leave in 2012 after a series of loan spells.
Spurs loaned Dos Santos out to Ipswich Town, Galatasaray and Racing Santander as he struggled to break into the firs -team, but they may be regretting their decision not to have allowed him more of a chance now.
The 25-year-old has gone on to become one of La Liga's best offensive players, with his creativity and trickery standing out.
Although Spurs need a ruthless goalscorer, they also could do with some much needed spark in their attacking midfield trio with many of their forward-thinking players looking off the past.
Aaron Lennon is showing signs of age and rarely offers a threat in attacking situations anymore, whilst Andros Townsend is also struggling for form - and question marks still remain over his ability.
Elsewhere Nacer Chadli may have hit a purple patch, but he still remains a player with a lot to prove. Erik Lamela is gradually adapting to English football, but is far off the finished product.
Dos Santos, meanwhile, has proven his worth internationally - standing out for Mexico at the World Cup this summer - and has become the creative fulcrum for his current Villarreal side.
His 11 goals in 32 games represents a decent return for a number 10, but his vision and touch would, no doubt, have helped Spurs' strike force if he had remained in North-London and Spurs' decision to sell him looks like an error.
Although it would be wrong to suggest Dos Santos was a roaring success on the pitch in England, he was only allowed 15 games at Spurs, meaning that he had very little time given to him to adjust.
When compared to the patience the side have shown in Lamela, it proves there has been a disparity - perhaps caused by the price-tags of the two - and if Spurs had shown just a little bit more faith in their agile youngster a few years ago, they may not have had so many troubles now.
