The Mexican international has impressed in Portugal so far.
This summer Watford made some bold moves in the transfer market. The Hornets sent plenty of the players that helped them get to the Premier League packing - including Mexican international Miguel Layun.
He was only signed by Watford in January on a four-and-a-half year deal and was a major marketing tool for the club as well, thanks to his high profile in Mexico.
He scored in the Premier League opener against Everton but was moved on at the end of August - joining Porto on loan for the rest of the season.
He has gone on to impress in Portugal. He has become a regular in the Porto first-team and has scored in his last two appearances for the club.
He has been speaking about his future this week, telling Portuguese publication Record:
"Of course I would like to continue at FC Porto.
"Porto are an important club, which everyone can see. But for the moment, I must remember that nothing is resolved and I have to enjoy the good time I'm going through.
"He (Quique Sanchez Flores) is a great coach and a good person. What he says is true, I do belong to Watford, but who has the last word is the FC Porto.
"But I will not let this external noise mess with my head. I am at Porto and I am happy here."
As reported by ESPN, when Layun made the move to Porto a €6 million (£4.25 million) buy-out clause was agreed with Watford over the player.
At the moment The Hornets seem to be coping alright without him and look like the promoted side most likely to stay in the Premier League this season.
So the cash windfall for Layun might just be snapped up at the end of the season.
