Leicester City have completed the signing of Belgian striker Franck Moussa. The 21-year-old joins the club on a free transfer after his contract at Southend United expired in the summer. The youngster had been on trial at QPR but has opted for a move to City. And, in the wake of Thai company King Power taking control of the club, Paolo Sousa has declared that he will continue to strengthen the squad before the end of the transfer window. The City boss said: 'I hope we can bring players in and we are looking always to be stronger. 'We are looking to add some players to the squad to become stronger, but not too much. We need to fix certain things in our squad and after that we can do exactly what we and I hope and expect us to do. 'I would like to have a bigger squad but very competitive with each other.' Sousa added. Having only passed his medical at the club yesterday, new signing Moussa is unlikely to feature against Middlesborough at the Walkers Stadium today.
