His debut in the
Oberliga Süd led the former amateur on 22 August 1954 to the local
Mainderby at Bieberer Berg in Offenbach. Egon Loy played well at the 1-0 away win and could secure a regular spot. He played 28 times for Eintracht and finished the season as fourth. The
Frank had a heavy knee injury and could only play one match in his second Eintracht season in 1955–56 and even in the 1956–57 campaign he had to fight for his comeback. The next season, he recovered. Egon Loy absolved all 30 Oberliga fixtures and finished third. On 17 November 1957, he got a call up for the South German selection against South West Germany. For the 1958–59 season former Offenbach manager
Paul Oßwald moved to Frankfurt. The squad from
Riederwald won the South German championship and lost not a point in the final round, advancing to the German championship final. On 28 June 1959, Loy and his team mates won the German championship 5–3 after overtime against
Kickers Offenbach in Berlin. In 1959–60, Frankfurt played in the
European Cup competition. The semi final matches against Scottish side
Rangers on 13 April and 5 May 1960 were especially impressive. After a sensational 6–1 win at home, Eintracht then won 6–3 at
Ibrox Park in Glasgow. The final match on 18 May at
Hampden Park against the title holder
Real Madrid was a football festival, despite the 7–3 loss.
Alfredo Di Stefano und
Ferenc Puskás showed why they were considered as the biggest stars of the competition. In the last three season of the Oberliga Süd from 1960–61 until 1962–63, Loy appeared in all 90 fixtures. In the next two campaigns of the new founded
Bundesliga, 1963–64 and 1964–65, the Schwabach native was still an unchallenged regular between the Eintracht pipes. He also played in Stuttgart the
DFB cup final on 13 June 1964 against
TSV 1860 München. The
Lions won 2-0 against Frankfurt. From 1965–66 on the former amateur national goal keeper
Peter Kunter who came from
Eintracht Wetzlar became number one of the
Eagles. Loy played his last Bundesliga match on 8 October 1966 against MSV Duisburg. In total, Egon Loy played 69 Bundesliga matches between 1963 and 1966. == Honours ==
