Andre Onana is set to spark a bidding war between Europe's elite in the summer, with Barcelona joining Chelsea as front-runners in the race for the Ajax keeper.
Both sides are looking light between the sticks, with Marc-Andre ter Stegen facing no competition for his place and Kepa Arrizabalaga out of form in West London.
The Spanish giants have had a rocky season so far, losing the La Liga lead to title rivals Real Madrid and being forced to switch managers.
Barca have conceded 13 more goals than Madrid this season, with ter Stegen only keeping six clean sheets in 23 league games. According to Sport, Barca are looking to Onana to come in and compete with their number one.
Ajax are reportedly after £35m for the Cameroon international, a price Chelsea may be reluctant to pay after splashing £72m on Kepa only 18-months-ago.
Onana came through Barcelona's academy, and rejected the chance to re-sign for the Catalans last summer, saying: 'It's my home, but it was not the right time to return.'
Since being sold in 2015, Onana has gone from strength to strength. He has been the Eredivisie side's first choice since arriving and played in the Champions League semi-finals last season.
The towering 23-year-old keeper in contracted to the Amsterdam side until 2022, but Barca's approach could be stronger this time around.
They opted to sign former Valencia keeper Neto after being turned down by Onana last summer, but he has not impressed enough to challenge ter Stegen.
