Barcelona have been told they'll need to pay £59 million if they're going to sign AS Monaco wonderkid Kylian Mbappe. Elsewhere, it's said Thomas Vermaelen will return to the Camp Nou from AS Roma in the summer.

According to French newspaper Le Parisien (h/t Daily Star's Joel Watson), Monaco won't settle for less than £51 million if they're to sell Mbappe, and they can add another £8 million if he signs a contract extension before he leaves.

Barcelona are mentioned alongside La Liga rivals Real Madrid as one of the teams interested in a move for Mbappe, while Premier League powerhouses Arsenal and Manchester City are also said to be in the hunt.

Sky Sports' Spanish football expert Guillem Balague recently reported the Frenchman may be convinced to remain with his Ligue 1 employers for the time being, however, rather than leave at such an early stage in his development:

The 18-year-old has exploded on the European stage this season and is one of the most highly rated teenagers on the continent after scoring 12 goals in 26 appearances across all competitions this season.

Mbappe is enjoying a breakout campaign on the French Riviera, and James Robson of the Manchester Evening News recently illustrated that elite-level interest in one of France's fastest rising prospects is nothing new:

Mbappe was in Guardiola's sights last summer. Sources say City were willing to pay upwards of £33m for him

Phil Thomas of The Sun reported Manchester City are willing to offer £50 million for Mbappe, which is a steep stepping-off point at which to begin what could become an expensive bidding auction.

Interest in Mbappe appears to have grown since his side lost 5-3 to the Citizens in the first leg of their UEFA Champions League round-of-16 meeting, where Squawka pointed to the Monaco man as a key ingredient:

Meanwhile, Vermaelen will reportedly be on his way back to the Camp Nou this summer after failing to impress the Roma coaching staff sufficiently during his season-long loan stay at the Stadio Olimpico.

The Belgian defender joined the Giallorossi until the end of the campaign last summer, but according to Calciomercato, the Serie A giants aren't interested in making the move a permanent one.

Vermaelen has struggled with injuries in recent years and has turned out for Roma on 10 occasions across all competitions this season.

It seems unlikely Barcelona will keep hold of the utility man, however, despite the fact his contract doesn't expire until 2019, meaning more transfer business could lie ahead for Vermaelen this summer.
