Arsenal have already completed one important piece of transfer business this summer, but don't expect them to call it quits with just Petr Cech.
It is with good reason too. The midfielder excelled at the recent European under-21 Championships, awarded by UEFA the Player of the Tournament prize, reported by Sport1.
He dominated against England in the group stages, and while his side lost in the final to Sweden on penalties, the tournament did wonders for his value.
There is a very real chance of Arsenal now being convinced to pay the £37 million release clause which exists in his contract, and if they do, his addition could be monumental.
Carvalho was described by Voetball International as 'Pirlo with power', for his confidence on the ball combined with his imposing frame.
Arsenal are searching for a partner for breakthrough star Francis Coquelin, and Carvalho would be just that.
With Petr Cech in goal, a defensive pairing of Laurent Koscielny and Per Mertesacker (with Gabriel pushing them) and a midfield screen of Carvalho and Coquelin, Arsenal could set defensive records.
No longer would they be a side able to be caught on the counter attack, but they would be a team with natural defensive balance, and the forward players would have license to roam and cause havoc for the opposition.
With Santi Cazorla, Jack Wilshere, Mesut Ozil, Theo Walcott, Olivier Giroud and Alexis Sanchez all eager to do so, Arsenal fans won't be blamed for getting excited about their prospects for next season and beyond.
All they need to do is match Sporting's demands, and complete the spine of their side, to set them on their way to overcome Jose Mourinho's Chelsea in 2015/16.
