Valencia’s progress to the lucrative Champions League group stage on Tuesday thanks to a 4-3 aggregate success against Monaco took them over a key hurdle in owner Peter Lim’s push to return the La Liga club to the continent’s elite.

Singapore billionaire Lim bought a majority stake in Valencia last year and while financial rules prevent him from splurging cash the club appear to have made some astute signings to lay the foundations for long-term success.

Lim’s faith in Portuguese coach Nuno also looks to be paying off, although Valencia cut it fine in the play-off second leg at Monaco, losing 2-1 having won 3-1 at the Mestalla last week.

Beaten finalists in Europe’s top club competition in 2000 and 2001, Valencia are back in the group stage for the first time since they reached the last 16 in season 2012-13.

The defeat in the principality served as a reminder that a top-class centre-back is needed to replace Argentina international Nicolas Otamendi, who joined Manchester City last week.

German World Cup winner Shkodran Mustafi is up to the task but doubts remain over whether 21-year-old Portuguese Ruben Vezo has the necessary pedigree and Valencia have until the transfer window closes at the end of the month to add to their ranks.

“After this match decisions must be made,” Nuno said.

“It’s time to talk, to sit down and calmly analyse the market, what is on offer, who you can sign while adhering to Financial Fair Play rules,” he added.

“Otamendi’s exit means we have to review the situation but if we do bring someone in they will have to contribute.”

If they manage to shore up the defence, Valencia look to have the talent in attack to help them make a decent run in Europe and possibly challenge for the La Liga title.
