Marco Silva was left very impressed by substitute Theo Walcott's performance, as the winger's introduction played a huge role in Everton's EFL Cup success over Watford on Tuesday night.
Walcott was brought on at half-time with the scores level at 0-0, and the 30-year-old put in a stellar display, helping the hosts see off the Hornets with two late goals, to book their place in the quarter-final of the competition.
The ex-Arsenal man provided the assist for Everton's opening goal which was headed home by Mason Holgate, and as reported by the Daily Mail, Silva was delighted with his super-sub's 'big impact'.
"Theo made a big impact again," he said. "The change we made at half-time had a big impact on our second half. We found the spaces more easily than in the first half because we started faster our build-up.
"He had the chance against West Ham because he showed me he deserved it and the performance he made was really good.
"[Against Watford] he did a very good second half, was really important. He is in a good moment and for sure he will help us in the next games as well."
Walcott had started three of the Toffees' previous four matches, and has been a bright spark during a difficult period for the Goodison Park faithful.
Everton have made a poor start to the new Premier League season, and were languishing in the relegation zone after eight games. However, a well-earned victory over West Ham lifted Everton up the table, but a last-gasp defeat to Brighton has left Silva's men with only ten points from their opening ten matches.
The Merseyside club host Tottenham Hotspur next week before a crucial trip to Saint Mary's, where the Toffees will face fellow strugglers Southampton, with both teams intent on lift themselves away from relegation danger.
