In terms of the contributions that Dr. Josef Venglos made to Celtic during his tenure as a manager, the trophy haul may have been bare but he did bring the iconic Ľubomír Moravčík to Parkhead in November 1998.
Aged 33 when he arrived in Glasgow, at the time, the signing of the Slovakian midfielder from German side Duisburg for £200,000 was mocked by some members of the press.
That quickly changed when 'Lubo' made his debut in a 6-1 demolition of Dundee at Celtic Park. Two weeks later, Moravčík cemented his cult-hero status at the club when he scored twice in a 5-1 thrashing of rivals Rangers at Parkhead.
He'd also score a memorable brace at Ibrox in a 3-0 win during the 2000/02 season.
Equally gifted on both feet, blessed with wonderful vision, and having a technique that made him stand head and shoulder above every other midfielder, Moravčík played a huge role in Celtic's two league titles, (00-01, 01-02), two league cups and Scottish Cup wins.
During a recent podcast with Football CFB, Celtic legend Henrik Larsson was asked about to describe just how good the Slovakian was.
Well, given the fact that the Swedish striker has played with the likes of Xavi, Iniesta, Ronaldinho, Messi, Ronaldo, Scholes, Rooney, etc, Larsson's statement that Moravčík is "definitely one of the best players I've ever played with" is quite special.
When asked if he knew who Moravčík was when he arrived at Celtic, Larsson said: "I didn't know anything about him to be honest, but it only takes one practice to see just...wow, he has something. Still, to this day, I don't know if he's left-footed or right-footed! That's crazy! I've never seen a player hitting the ball as sweetly with both feet.
"The vision he had to see the game, see runs was just fantastic. He's most definitely one of the best players I've ever played with. Also, he's a great guy. I bump into him every now and then and it's always a pleasure to speak with him."
The whole interview with 'The King of Kings' is fascinating as he covers his career in depth including the importance of stopping Rangers' bid for a 10-in-a-row, his international career at Sweden, the highs and lows of his time at Parkhead, winning the Champions League at Barcelona, playing for Manchester United, and his managerial career.
