Sergio Aguero's first Barcelona start at Camp Nou ended prematurely as he was substituted before half-time against Deportivo Alaves on Saturday.

The former Manchester City striker, who arrived on a free transfer in July, led the line in Barca's first game since the departure of Ronald Koeman this week.

Aguero went down clutching his chest just before the break and appeared to be in some discomfort as he was tended to by the medical team.

Although the stretcher was initially called for, the Argentina international was able to get to his feet and walk from the pitch to be replaced by Philippe Coutinho in the 41st minute.

Sergi Barjuan was taking temporary charge of the hosts, who had lost three of their past four LaLiga matches.
