Ok guys - just to keep you posted - this is exactly what happened (giving a brief since many people may face the same issues).
Landed on time - 1.30 pm (Munich Airport)
Walk and pass airport Immigration - 2.00 pm
I travelled very light (considering there was no place to keep my bags) - had one small haversack
Based on some suggestions (called for a taxi) - you can easily book the same online - lots of websites with a standard charge (they only take a confirmation and don't charge your card - you can pay by cash at the end of your journey) - The company driver was holding a board with my name on it - Taxi fare to the arena - 58 euros
Travel Time to the arena (till when the traffic for match started - about 1 km from the turn-off to the arena) - 2.20 pm
Traffic - and travel to the gate - 2.40 pm (drop off near the gate)
Entry to the arena - 2.45 pm
Had beer and sausages and still had time to see the even the warm-up
Absolutely brilliant - thanks to everyone who helped me - hope this helps some people
