Barcelona have reportedly been left frustrated as their attempts to sign Mohamed Salah, Erling Braut Haaland and Robert Lewandowski will be blocked by La Liga.
Xavi's side are set for an overhaul in the summer with it being the Spaniard's first pre-season in charge at Camp Nou, and the Catalan giants have been linked with many top European stars.
Salah is currently leading the goalscoring chart in the Premier League, having netted 20 goals in 27 Liverpool appearances so far this campaign, and his future at Anfield is in doubt after he reportedly turned down the club's latest contract renewal.
However, Marca reports that Barcelona will struggle to sign Salah or other top targets like Borussia Dortmund's Haaland and Bayern Munich's Lewandowski due to their precarious financial situation.
Barca's spending limit has increased from £81m to £121m, meaning that they need to provide evidence of greater investment to show La Liga their longer-term stability plan.
Xavi will want to bolster his squad, and the club's new contract with sponsors Spotify will help but they are likely to need more investment to achieve signings such as Salah.
