The defender impressed in the 2-1 win over Bournemouth.
With Phil Jagielka out injured and Ramiro Funes Mori still serving a ban following his sending off in the Merseyside derby, Everton were short on numbers for the clash with Bournemouth this weekend.
That led to them recalling Pennington from his loan spell at Walsall, and Roberto Martinez then electing to start him alongside John Stones on Saturday.
He did not let his manager down either, with an assured display in the heart of the defence in his side’s eventual 2-1 win. And speaking about the experience, Pennington says it was a surreal and proud moment for him.
“It was a surreal moment for me,” he told evertonfc.com. “It was a proud moment for my family and I and I think I did well. I am just grateful that we got the win on my Premier League debut. The three points were nice.
“It was different to what I was experiencing at Walsall but it is always a challenge playing a competitive game of football, hopefully it is the first of many.”
The young defender will now be hoping he is handed his chance to further impress in the remaining games.
His performance against the Cherries will certainly not have done him any harm as he handled the step up in quality comfortably.
With the Blues having nothing left to play for as well, there is no reason for Roberto Martinez not to decide to stick by him following an impressive debut either.
