SATISFYING though it was, Scotland's 1-0 friendly win in Warsaw this March was the football equivalent of tuning into an episode of Taggart minus Mark McManus or going to a Queen and Paul Rodgers gig.

It just wasn't the same without the headline act.

Fortunately for all lovers of football, and perhaps unfortunately for the Tartan Army, Robert Lewandowski is ready to resume his role as the spearhead of Poland when Scotland return to the national stadium on Tuesday.

The 26-year-old was a Borussia Dortmund player when he missed out in March due to a knee injury, but will take to the field as an authentic member of football's elite, the ink still wet on his multi-million contract at FC Hollywood (aka Bayern Munich). Scrutiny goes with the territory at the Allianz Arena, though, and seasoned Bundesliga watchers are still making up their mind on whether this most eagerly awaited of internal German transfers is a success.

Lewandowski notched the third, fourth, sixth and seventh goals of Poland's 7-0 dismantling of hapless new boys Gibraltar in Faro in September, taking his international tally to 23 in 62 appearances. But in his 11 club matches to date, he has only scored four, two of which came last week against relegation contenders Hannover '96.

Scotland assistant manager Mark McGhee, something of a German expert after his time spent at Hamburg during the mid-80s, is one man who reckons Lewandowski still has work to do to convince anyone that he is a clear upgrade on Mario Mandzukic, the Croatian - now at Atletico Madrid - who won the Champions League with Bayern but twice drew a blank against Scotland in World Cup qualifying ties.

"I don't think he makes Poland a totally different team but he does make a huge difference to them," said McGhee. "It's like listening to Chris Coleman talking about Wales with or without Gareth Bale and the effect his presence has on everyone around him. He is obviously a star player for them and there is also the impact it can have on the opposition knowing they have a player of that stature.

"But I don't think we were kidded by the fact we got the result over there; we were well aware he wasn't playing. I can't sit here and say if he'd played we would still have beaten them ... but the result in Poland was a great result, regardless of whether he played or not.

"He is the same as Mandzukic in my opinion. I think they are of a similar level, in the next batch below the absolute best. Our defence have seen off Mandzukic already so I wouldn't imagine they'll have any fears about facing Lewandowski. I know Bayern replaced Mandzukic with Lewandowski last summer but there is always a bit of refreshing, a bit of contractual stuff and agents which plays a part in players moving on or being replaced. I don't think they have become weaker but I'm not sure they have got stronger.

"I think he has still to prove himself. I'm not sure we have seen enough of him in those really big games to know yet. Bayern Munich don't make many mistakes though and they've invested a lot in him."

Lewandowski's skill set is certainly more refined than that of the archetypal, old-fashioned target man. For a start he stands only 6ft 1in tall, with pace and movement among his greatest assets. His power is generated by a muscular frame which has earned him the nickname of "the Body", along with Australian model Elle Macpherson. The son of a judoka and volleyball player, and with a wife, Anna Stachurska, who is a karate professional, few players boast greater physical condition. He can mix it too - no Dortmund player committed more fouls than he last season.

While Scotland won't obsess on his talents too much, Gordon Strachan's backroom staff are well aware that he thrives on precisely the kind of crosses which have caused difficulty for Scotland's defence. At least winger Jakub Blaszczykowski, Poland's next most recognised player, will be unavailable to provide the ammunition in their 4-4-1-1 shape due to the after effects of a knee injury. "It will be more of a head to head," said McGhee. "Man against man, can we be better than them?"
