Spanish champions Barcelona have exercised the buy-back clause to re-sign midfielder Denis Suarez from Villarreal, the Catalan club announced on Monday.

The attacking midfielder made 48 appearances during his one season at the El Madrigal and played a key role in helping the club finished fourth in La Liga to earn a Champions League playoff spot and reach the Europa League semi-finals.
The former Manchester City player will undergo a medical on Tuesday and will be unveiled on Wednesday.

Leicester poised to sign CSKA Moscow striker Musa
Nigerian striker Ahmed Musa is set to complete a move to Premier League champions Leicester City from Russian club CSKA Moscow subject to a medical, according to the player's agent.
The 23-year-old, who scored 13 league goals in 29 league appearances last season as the club won the Russian title, was linked by British media to Leicester City in January and had also attracted interest from Southampton and West Ham United.
The fee for the Nigerian international is in the region of 16 million pounds ($21.20 million) according to British media reports, which would be a club record.
"Everything has been finalised and Musa will be in England for his medical on Wednesday," the player's agent Tony Harris told BBC Sport.
CSKA Moscow coach Leonid Slutsky was also optimistic that Musa would flourish in England.
"He'll be leaving on Tuesday," Slutsky told Russian media.
"If you look at the way things are done over there, you'll see he is a player just made for English football."
Leicester City also announced the signing of midfielder Nampalys Mendy from Nice on Sunday.
Midfielder Jurado swaps Watford for Spanish side Espanyol
Attacking midfielder Jose Manuel Jurado has left English Premier League side Watford for Spain's Espanyol, where he will reunite with former manager Quique Sanchez Flores.
The 30-year-old Jurado, who joined Watford from Spartak Moscow in July 2015, has signed a three-year contract with the La Liga club, Espanyol said on their website.
Jurado came through the ranks at Real Madrid but signed for local rivals Atletico Madrid in Aug. 2006. He spent three seasons at Atletico and one on loan at Real Mallorca, winning the 2009-10 edition of the Europa League with the former.
The midfielder's time at Atletico ended in Aug. 2010, when he moved to German side Schalke 04 on a two-year contract.
Jurado won the German Cup and Super Cup with Schalke in the 2010-11 season before moving to Moscow, where he spent three seasons before heading to England.
Sanchez Flores was sacked by Watford in May, despite guiding the club to a 13th-place finish in the Premier League and the semi-finals of the FA Cup.
The Spaniard, who was named coach of Espanyol last month, was replaced by former Inter Milan coach Walter Mazzarri by the English club.
