Posh have signed Samuelsen on loan from West Ham until January, and there are high hopes for the attacking midfielder at the ABAX Stadium.
Westley was in attendance at one of West Ham’s recent reserve matches, and the former Stevenage boss says that Samuelsen was the most notable talent on display in the match.
“Martin Samuelsen was the stand out player when I watched West Ham reserves recently," he said.
"I thank West Ham for letting him come here and I can see him playing in all sorts of positions for us. He could play the number 10 role, he could play to the left of the midfield diamond and he could play on the left of a three-man attack.
“Martin likes to come in from the left side to attack and he’s a very exciting prospect.”
Samuelsen was named on the Posh bench for their midweek win over Barnsley, but he did not make it onto the pitch in that fixture.
The Norwegian youngster instead watched from the sidelines, as his new teammates picked up a 3-2 win over the Tykes.
That victory has lifted Posh to the verge of the play-off spaces, and Westley will be hoping that Samuelsen’s addition can give his side even more attacking quality.
Peterborough are the top scorers in the Football League, having netted 42 times in 19 matches this season.
Posh’s next match comes against Scunthorpe United on Saturday, and Samuelsen could be in line to make his debut, with Jermaine Anderson suspended.
