Manchester United and Chelsea appear to face significant competition for Sevilla left-back Alberto Moreno.
According to the Daily Mail, Premier League newcomers Cardiff City are interested in the 21-year-old - who reportedly has a buyout clause of £25 million at Ramón Sánchez Pizjuán - and could be set to open the bidding for his services.
The same reports also state that the Welsh side, who appear to have adapted to life in the top-flight with admirable ease, hold fears that the aforementioned title rivals could move to outbid them.
Both Manchester United and Chelsea have been recently linked with the Spain international, who has already earned two senior international caps for La Roja under the tutelage of the experienced Vicente del Bosque.
Manchester United are believed to be on the hunt for a new left-back, with current starter Patrice Evra's contract set to expire at the end of the current campaign and the duo of Alexander Buttner and Fabio da Silva unlikely to sufficiently fill the void that would be left by his seemingly imminent departure.
Chelsea's need to secure the signing of a new left-back, however, appears to have reduced somewhat in recent weeks with the surprising resurgence of former Marseille star Cesar Azpilicueta keeping England international Ashley Cole - still widely considered to be the best in the world in his favoured position - firmly planted on the substitute's bench.
If all three clubs were indeed to enter a bidding war for Moreno, you would have to presume that a move to either Stamford Bridge or Old Trafford would be far more appealing than a potential switch to South Wales.
