The Ecuadorean played for 20 minutes against Reading in a friendly today.
It may be the international break but that does not mean all rest and no play for Premier League players.
The players who are not away on international duty with their countries are still being put through their paces. They might be youngsters, players no longer considered worthy of a call-up or indeed those coming back from injury, too short notice to be given a role in the international set-up immediately.
That was certainly the case for West Ham United as they took on a Reading side in a behind-closed-doors friendly earlier today.

The Ecuadorean striker picked up a nasty knee problem earlier in the season and has been out of action since suffering the problem against Astra Giurgiu in the Europa League at the start of August.
In the wake of his injury there were many controversies. He told media in his homeland that he was not pleased with the way West Ham had treated him since his injury. He then came out to apologise about that statement and all is believed to be well.
He has recently returned to full training and came on today, replacing new signing Michail Antonio in the 71st minute.
West Ham scored thrice in the game, with the goals coming from Mauro Zarate (2) and Andy Carroll, from a Valencia assist. Unfortunately West Ham lost the game 4-2, but the return of Valencia will be the big news for Hammers fans.
