Sparta Praha loaned Hong Quan to Thanh Hoa "for free".
According to the Thanh Hoa team's leadership, they secured striker Mac Hong Quan on loan from Sparta Praha "for free," without paying a transfer fee. The contract is for three months and ends after the 2013 V-League season.
After this deadline, if Thanh Hoa is satisfied with Mac Hong Quan's performance and contributions to the team, they will proceed with the official transfer of the player.

At that time, Thanh Hoa only had to pay the Czech Republic team about 200,000 USD in training fees because Mac Hong Quan was only 21 years old.
Currently, since the season in the Czech Republic has ended and Mac Hong Quan has also finished his high school graduation exams, he needs a suitable competitive environment to maintain his form and secure a place in the Vietnam U23 team participating in the 27th SEA Games.
Therefore, after Thanh Hoa Club contacted them, Mac Hong Quan and his family expressed their wishes, and they were accepted by Sparta Praha Club.
After returning to Vietnam with his father to prepare for training with the U23 national team, Mac Hong Quan officially signed a contract yesterday to play for Thanh Hoa in the second half of the 2013 V-League season.
With Mac Hong Quan's arrival, Thanh Hoa also terminated the contract with striker Patiyo to make room for the third foreign player slot for Patrick Oboya, a former striker of MFK Ruzomberok (Slovakia). Previously,
Patrick Oboya also played for Banik Most, the team of another Vietnamese-American player who is a close friend of Mac Hong Quan, Michal Nguyen.
Looking ahead, Mac Hong Quan's first match for Thanh Hoa will be an away game against Dong Nai in Round 12, the first round of the second half of the 2013 V-League season.
At Thanh Hoa Club, Mac Hong Quan may not need much time to adapt because the team's current head coach, Mai Duc Chung, a member of the National Coaches Council, is the same person who introduced Mac Hong Quan to the VFF, which subsequently led to the player being called up to play for the U22 national team, and later the senior national team.
