First with William Saliba and now with Fofana, the manager has had to see two of his starlets leave early for a Premier League move, which has helped the French club's bank account, but he feels they could have got more next year. Thomas is a boy I remember playing on the B team with Saul [Niguez]. The club are a bit like family and friends [to him].
"He needs that year of transition and we are trying to make the right decisions for him to give him the best transitional year to have the player we want in our future".
On signing Partey, Arteta was effusive in his praise of the 27-year-old: 'We have been watching Thomas for a while, so we're now delighted to add such a high-quality player to our squad.
The 19-year-old's surprise omission after finally arriving at the Emirates this summer and a failed second loan move back to his former club before the overseas deadline means he is likely to struggle for game time this season.
After thrashing Granada 6-1 on the opening day, they have posted successive goalless draws against Huesca and Villarreal.
Simeone has hinted that he could start Luis Suarez, Diego Costa and Joao Felix together to get his side's attack going again, saying Portuguese striker Felix must strive to bring his global form at the club level.
He's there now, and if he does become the player Puel thinks he will, then it's the Foxes who will be laughing their way to the bank if they ever decide to sell him. We'll see at what moment, what situation and in what state each one is, ' Simeone said.
"He has talent and he can appear at any moment, but what I saw with Portugal, where he showed commitment, intention, enthusiasm for what the team needed - that speaks highly of him and it's what we also need from him".
