Liverpool have confirmed the signing of Sevilla forward Luis Alberto. A statement on the club's official website reads:

"Liverpool Football Club have today completed the signing of Spanish forward Luis Alberto from Sevilla, subject to international clearance. The 20-year-old, who can play anywhere across the attacking line, has penned a long-term contract after passing a medical at Melwood."

The Reds' boss, Brendan Rodgers, told the site he was excited by the young Spaniard's arrival. The former Swansea City manager said, "We are all delighted that Luis has decided to join Liverpool. He has the correct footballing profile and mentality to be a Liverpool player. I look forward to working with him to develop his talent and he joins a group of young exciting players at our club."

Alberto spent the 2012/13 season on loan to Spanish champions Barcelona's B team, for whom he scored 11 goals. The Catalans declined to sign the forward on a permanent basis though, given the wealth of options already at the club. The BBC believes a fee of £6.8m was exchanged.

Meanwhile, the Mail Online believes Liverpool have agreed a £9m fee with Sunderland for goalkeeper Simon Mignolet.

The report claims the Anfield side have beaten Arsenal to the 24-year-old Belgian international. Neither the player nor the clubs involved have commented on the deal so far but it is expected a confirmation will be released next week.

The Black Cats' boss, Paolo di Canio, is thought to want to re-invest funds from the sale of Mignolet into young American forward Jozy Altidore.

Mignolet's role at Merseyside is likely to be as a back-up to Spain international Pepe Reina, assuming the 30-year-old remains at Anfield for the new season. The Madrid-born former Barcelona goalkeeper has been linked to the club of his youth as a possible replacement for the Catalans' outgoing No 1, Victor Valdes.

However, with Valdes having confirmed his position at the Nou Camp for this season, Reina has re-affirmed his commitment to Brendan Rodgers' side. That said, Liverpool will have to offer top-level opportunities to retain Reina. The Spaniard has been quoted as saying he will move to a "bigger" club to ensure more starting berth with the Spanish national side.

Rodgers has tried to be pro-active in the transfer market this summer, with the signing of Ivory Coast international Kolo Toure announced early. However, since then, the Northern Irishman has had a few problems. Moves to bring Armenia international Henrikh Mkhitaryan and Spaniard Iago Aspas have stalled over contractual difficulties; over £30m will be spent on those two, if the deals are confirmed.
