The Championship leaders have sent scouts to watch the Spaniard play with Osasuna.

Merida is in his second season at Osasuna, who were relegated from La Liga last season.

The 27-year-old has made 25 appearances for them, scoring two goals.

Merida was a product of the Barcelona youth academy.

Then he joined the Arsenal set-up, where he spent five years.

He made only 16 first-team appearances but is remembered a stunning goal in a 2-1 League Cup win over Liverpool in October 2009.
